+
+0.24 2011-11-09
+ - Require Text::Balanced >= 0.97 to prevent bad surprises (reported by Ryan Golhar)
+
+0.23 2011-10-28
+ - Arrays of number-containing strings are now handled properly (RT bug
+ #71988, patch by dheiman)
+
+0.22 2011-10-09
+ - The run() method now accepts an array of strings as input
+ - New run_from_file() method to read and execute commands from an R file
+ - Better detection of R errors by using the R exception system (issue
+ reported by Mike Imelfort)
+ - Updated error handling mechanism to detect R syntax errors in addition
+ to R runtime errors
+ - Tests now work for different locales (issue reported by Knut Behrends)
+
+0.21 2011-09-04
+ - Tweaked the regular expressions that parse the R output stream for added
+ speed and robustness
+
+0.20 2011-08-31
+ - Refactored the entire R communication bridge to avoid writing and reading
+ files. All data is now stored in memory and passed by pipes. This fixes
+ bug RT #11309, #11918, #66190 and #70314
+ - Refactored the communications in shared mode
+ - Put platform-specific code and legacy code in separate modules
+
+0.10 2011-08-27
+ - Refactoring to remove old code doing platform-specific operations.
+ - Lots of code cleanup
+ - Removed the now useless r_dir and tmp_dir options of new()
+ - Fix for change of dir bug (RT #6724). Also fixes missing synopsis file (RT #70307)
+ - More subtle cleanup procedure (RT #70392)
+
+0.09 2011-08-23
+ - Changes in the new() method:
+ * it automatically calls start()
+ * it has the 'shared' option to start a shared bridge
+ - More portable filenames (RT #70391)
+ - Added convenience methods:
+ * run() replaces send() and read() and checks for errors (RT #70361)
+ * get() fetches the values in an R vector (RT #70361)
+ * set() assigns values to an R vector
+ - Fixed a bug in the unlock() method
+ - Removed the R() and error() methods and renamed some other. These changes
+ should be transparent and backward compatible

+ touchups, small code cleanups, version numbering, better README generation,
+ Git and bug tracker URLs
+
+0.08 2011-03-01

+NAME
+ Statistics::R - Perl interface with the R statistical program
+
+DESCRIPTION
+ *Statistics::R* is a module to controls the R interpreter (R project for
+ statistical computing: <http://www.r-project.org/>). It lets you start
+ R, pass commands to it and retrieve the output. A shared mode allow to
+ have several instances of *Statistics::R* talk to the same R process.
+
+ The current *Statistics::R* implementation uses pipes (for stdin, stdout
+ and and stderr) to communicate with R. This implementation should be
+ more efficient and reliable than that in previous version, which relied
+ on reading and writing files. As before, this module works on GNU/Linux,
+ MS Windows and probably many more systems.
+
+SYNOPSIS
+ use Statistics::R;
+
+ # Create a communication bridge with R and start R
+ my $R = Statistics::R->new();
+
+ # Run simple R commands
+ my $output_file = "file.ps";
+ $R->run(qq`postscript("$output_file" , horizontal=FALSE , width=500 , height=500 , pointsize=1)`);
+ $R->run(q`plot(c(1, 5, 10), type = "l")`);
+ $R->run(q`dev.off()`);
+
+ # Pass and retrieve data (scalars or arrays)
+ my $input_value = 1;
+ $R->set('x', $input_value);
+ $R->run(q`y <- x^2`);
+ my $output_value = $R->get('y');
+ print "y = $output_value\n";
+
+ $R->stop();
+
+METHODS
+ new()
+ Build a *Statistics::R* bridge object between Perl and R. Available
+ options are:
+
+ r_bin
+ Specify the full path to R if it is not automatically found. See
+ INSTALLATION.
+
+ shared
+ Start a shared bridge. When using a shared bridge, several
+ instances of Statistics::R can communicate with the same unique
+ R instance. Example:
+
+ use Statistics::R;
+
+ my $R1 = Statistics::R->new( shared => 1);
+ my $R2 = Statistics::R->new( shared => 1);
+
+ $R1->set( 'x', 'pear' );
+ my $x = $R2->get( 'x' );
+ print "x = $x\n";
+
+ Do not call the *stop()* method is you still have processes that
+ need to interact with R.
+
+ run()
+ First, start() R if it is not yet running. Then, execute R commands
+ passed as a string and return the output as a string. If your
+ command fails to run in R, an error message will be displayed.
+
+ Example:
+
+ my $out = $R->run( q`print( 1 + 2 )` );
+
+ If you intend on runnning many R commands, it may be convenient to
+ pass an array of commands or put multiple commands in an here-doc:
+
+ # Array of R commands:
+ my $out1 = $R->run(
+ q`a <- 2`,
+ q`b <- 5`,
+ q`c <- a * b`,
+ q`print("ok")`
+ );
+
+ # Here-doc with multiple R commands:
+ my $cmds = <<EOF;
+ a <- 2
+ b <- 5
+ c <- a * b
+ print('ok')
+ EOF
+ my $out2 = $R->run($cmds);
+
+ To run commands from a file, see the run_from_file() method.
+
+ The output you get from run() is the combination of what R would
+ display on the standard output and the standard error, but the order
+ may differ. When loading modules, some may write numerous messages
+ on standard error. You can disable this behavior using the following
+ R command:
+
+ suppressPackageStartupMessages(library(library_to_load))
+
+ run_from_file()
+ Similar to run() but reads the R commands from the specified file.
+ Internally, this method uses the R source() command to read the
+ file.
+
+ set()
+ Set the value of an R variable (scalar or arrayref). Example:
+
+ $R->set( 'x', 'pear' );
+
+ or
+
+ $R->set( 'y', [1, 2, 3] );
+
+ get()
+ Get the value of an R variable (scalar or arrayref). Example:
+
+ my $x = $R->get( 'x' ); # $y is an scalar
+
+ or
+
+ my $y = $R->get( 'y' ); # $x is an arrayref
+
+ start()
+ Explicitly start R. Most times, you do not need to do that because
+ the first execution of run() or set() will automatically call
+ start().
+
+ stop()
+ Stop a running instance of R.
+
+ restart()
+ stop() and start() R.
+
+ bin()
+ Get or set the path to the R executable.
+
+ is_shared()
+ Was R started in shared mode?
+
+ is_started()
+ Is R running?
+
+ pid()
+ Return the pid of the running R process
+
+INSTALLATION
+ Since *Statistics::R* relies on R to work, you need to install R first.
+ See this page for downloads, <http://www.r-project.org/>. If R is in
+ your PATH environment variable, then it should be available from a
+ terminal and be detected automatically by *Statistics::R*. This means
+ that you don't have to do anything on Linux systems to get
+ *Statistics::R* working. On Windows systems, in addition to the folders
+ described in PATH, the usual suspects will be checked for the presence
+ of the R binary, e.g. C:\Program Files\R. If *Statistics::R* does not
+ find R installation, your last recourse is to specify its full path when
+ calling new():
+
+ my $R = Statistics::R->new( r_bin => $fullpath );
+
+ You also need to have the following CPAN Perl modules installed:
+
+ Text::Balanced (>= 1.97)
+ Regexp::Common
+ IPC::Run
+

+=head1 NAME
+
+Statistics::R - Perl interface with the R statistical program
+
+=head1 DESCRIPTION
+
+I<Statistics::R> is a module to controls the R interpreter (R project for statistical
+computing: L<http://www.r-project.org/>). It lets you start R, pass commands to
+it and retrieve the output. A shared mode allow to have several instances of
+I<Statistics::R> talk to the same R process.
+
+The current I<Statistics::R> implementation uses pipes (for stdin, stdout and
+and stderr) to communicate with R. This implementation should be more efficient
+and reliable than that in previous version, which relied on reading and writing
+files. As before, this module works on GNU/Linux, MS Windows and probably many
+more systems.
+
+=head1 SYNOPSIS
+
+ use Statistics::R;
+
+ # Create a communication bridge with R and start R
+ my $R = Statistics::R->new();
+
+ # Run simple R commands
+ my $output_file = "file.ps";
+ $R->run(qq`postscript("$output_file" , horizontal=FALSE , width=500 , height=500 , pointsize=1)`);
+ $R->run(q`plot(c(1, 5, 10), type = "l")`);
+ $R->run(q`dev.off()`);
+
+ # Pass and retrieve data (scalars or arrays)
+ my $input_value = 1;
+ $R->set('x', $input_value);
+ $R->run(q`y <- x^2`);
+ my $output_value = $R->get('y');
+ print "y = $output_value\n";
+
+ $R->stop();
+
+=head1 METHODS
+
+=over 4
+
+=item new()
+
+Build a I<Statistics::R> bridge object between Perl and R. Available options are:
+
+
+=over 4
+
+=item r_bin
+
+Specify the full path to R if it is not automatically found. See L<INSTALLATION>.
+
+=item shared
+
+Start a shared bridge. When using a shared bridge, several instances of
+Statistics::R can communicate with the same unique R instance. Example:
+
+ use Statistics::R;
+
+ my $R1 = Statistics::R->new( shared => 1);
+ my $R2 = Statistics::R->new( shared => 1);
+
+ $R1->set( 'x', 'pear' );
+ my $x = $R2->get( 'x' );
+ print "x = $x\n";
+
+Do not call the I<stop()> method is you still have processes that need to interact
+with R.
+
+=back
+
+
+=item run()
+
+First, start() R if it is not yet running. Then, execute R commands passed as a
+string and return the output as a string. If your command fails to run in R, an
+error message will be displayed.
+
+Example:
+
+ my $out = $R->run( q`print( 1 + 2 )` );
+
+If you intend on runnning many R commands, it may be convenient to pass an array
+of commands or put multiple commands in an here-doc:
+
+ # Array of R commands:
+ my $out1 = $R->run(
+ q`a <- 2`,
+ q`b <- 5`,
+ q`c <- a * b`,
+ q`print("ok")`
+ );
+
+ # Here-doc with multiple R commands:
+ my $cmds = <<EOF;
+ a <- 2
+ b <- 5
+ c <- a * b
+ print('ok')
+ EOF
+ my $out2 = $R->run($cmds);
+
+To run commands from a file, see the run_from_file() method.
+
+The output you get from run() is the combination of what R would display on the
+standard output and the standard error, but the order may differ. When loading
+modules, some may write numerous messages on standard error. You can disable
+this behavior using the following R command:
+
+ suppressPackageStartupMessages(library(library_to_load))
+
+
+=item run_from_file()
+
+Similar to run() but reads the R commands from the specified file. Internally,
+this method uses the R source() command to read the file.
+
+=item set()
+
+Set the value of an R variable (scalar or arrayref). Example:
+
+ $R->set( 'x', 'pear' );
+
+or
+
+ $R->set( 'y', [1, 2, 3] );
+
+
+=item get()
+
+Get the value of an R variable (scalar or arrayref). Example:
+
+ my $x = $R->get( 'x' ); # $y is an scalar
+
+or
+
+ my $y = $R->get( 'y' ); # $x is an arrayref
+
+=item start()
+
+Explicitly start R. Most times, you do not need to do that because the first
+execution of run() or set() will automatically call start().
+
+=item stop()
+
+Stop a running instance of R.
+
+=item restart()
+
+stop() and start() R.
+
+=item bin()
+
+Get or set the path to the R executable.
+
+=item is_shared()
+
+Was R started in shared mode?
+
+=item is_started()
+
+Is R running?
+
+=item pid()
+
+Return the pid of the running R process
+
+=back
+
+=head1 INSTALLATION
+
+Since I<Statistics::R> relies on R to work, you need to install R first. See this
+page for downloads, L<http://www.r-project.org/>. If R is in your PATH environment
+variable, then it should be available from a terminal and be detected
+automatically by I<Statistics::R>. This means that you don't have to do anything
+on Linux systems to get I<Statistics::R> working. On Windows systems, in addition
+to the folders described in PATH, the usual suspects will be checked for the
+presence of the R binary, e.g. C:\Program Files\R. If I<Statistics::R> does not
+find R installation, your last recourse is to specify its full path when calling
+new():
+
+ my $R = Statistics::R->new( r_bin => $fullpath );
+
+You also need to have the following CPAN Perl modules installed:
+

+Statistics::R::Legacy - Legacy methods for Statistics::R
+
+=head1 DESCRIPTION
+
+This module contains legacy methods for I<Statistics::R>. They are provided
+solely so that code that uses older versions of I<Statistics::R> does not crash
+with recent version. Do not use these methods in new code!
+
+Some of these legacy methods simply had their name changed, but some others were
+changed to do nothing and return only single value because it did not make sense
+to keep these methods as originally intended anymore.
+

+
+=item win32_space_quote( )
+
+Takes a path and return a path that is surrounded by double-quotes if the path

+
+ C:\Program Files\R\bin\x64
+
+becomes
+
+ C:\Program\ Files\R\bin\x64
+
+=item win32_double_bs
+
+Takes a path and return a path where each backslash was replaced by two backslashes.
