\r
48 are \code{"latex"} or \code{"html"}.
\r
49 Default value is \code{"latex"}.}
\r
50 \item{file}{Name of file where the resulting code should be saved. If
\r
51 \code{file=""}, output is displayed on screen. Note that the
\r
52 function also (invisibly) returns a character vector of the results
\r
53 (which can be helpful for post-processing).
\r
54 Default value is \code{""}.}

55 \item{append}{If \code{TRUE} and \code{file!=""}, code will be

56 appended to \code{file} instead of overwriting \code{file}.
\r
57 Default value is \code{FALSE}.}
\r
58 \item{floating}{If \code{TRUE} and \code{type="latex"}, the resulting
\r
59 table will be a floating table (using, for example,
\r
60 \code{\\begin\{table\}} and \code{\\end\{table\}}). See
\r
61 \code{floating.environment} below.
\r
62 Default value is \code{TRUE}. }
\r
63 \item{floating.environment}{If \code{floating=TRUE} and
\r
64 \code{type="latex"}, the resulting table uses the specified floating
\r
65 environment. Possible values include \code{"table"}, \code{"table*"},
\r
66 and other floating environments defined in LaTeX packages.
\r
67 Default value is \code{"table"}.}
\r
68 \item{table.placement}{If \code{floating=TRUE} and
\r
69 \code{type="latex"}, the floating table will have placement given by
\r
70 \code{table.placement} where \code{table.placement} must be
\r
71 \code{NULL} or contain only elements of
\r
72 \{"h","t","b","p","!","H"\}.
\r
73 Default value is \code{"ht"}.}
\r
74 \item{caption.placement}{The caption will be have placed at the bottom
\r
75 of the table if \code{caption.placement} is \code{"bottom"} and at
\r
76 the top of the table if it equals \code{"top"}.
\r
77 Default value is \code{"bottom"}.}
\r
78 \item{caption.width}{The caption will be placed in a \code{"parbox"}
\r
79 of the specified width if \code{caption.width} is not \code{NULL} and
\r
80 \code{type="latex"}. Default value is \code{NULL}.}
\r
81 \item{latex.environments}{If \code{floating=TRUE} and
\r
82 \code{type="latex"}, the specificed latex environments (provided as
\r
83 a character vector) will enclose the tabular environment.
\r
84 Default value is \code{"center"}. }
\r
85 \item{tabular.environment}{When \code{type="latex"}, the tabular
\r
86 environment that will be used.
\r
87 Defaults to \code{"tabular"}.
\r
88 When working with tables that extend more than one page, using
\r
89 \code{tabular.environment="longtable"} and the LaTeX package
\r
90 \code{"longtable"} (see Fairbairns, 2005) allows one to typeset them
\r
91 uniformly. Note that \code{"floating"} should be set to
\r
92 \code{"FALSE"} when using the \code{"longtable"} environment.}
\r
93 \item{size}{An arbitrary character vector intended to be used to set
\r
94 the font size in a LaTeX table. The supplied value (if not
\r
95 \code{NULL}) is inserted just before the tabular environment
\r
97 Default value is \code{NULL}. }
\r
98 \item{hline.after}{When \code{type="latex"}, a vector of numbers
\r
99 between -1 and \code{"nrow(x)"}, inclusive, indicating the rows
\r
100 after which a horizontal line should appear. If \code{NULL} is used
\r
101 no lines are produced.
\r
102 Default value is \code{c(-1,0,nrow(x))} which means draw a line
\r
103 before and after the columns names and at the end of the
\r
104 table. Repeated values are allowed.}
\r
105 \item{NA.string}{String to be used for missing values in table
\r
107 Default value is \code{""}.}
\r
108 \item{include.rownames}{logical. If \code{TRUE} the rows names is
\r
110 Default value is \code{TRUE}.}
\r
111 \item{include.colnames}{logical. If \code{TRUE} the columns names is
\r
113 Default value is \code{TRUE}.}
\r
114 \item{only.contents}{logical. If \code{TRUE} only the rows of the
\r
116 Default value is \code{FALSE}. }
\r
117 \item{add.to.row}{a list of two components. The first component (which
\r
118 should be called 'pos') is a list contains the position of rows on
\r
119 which extra commands should be added at the end, The second
\r
120 component (which should be called 'command') is a character vector
\r
121 of the same length of the first component which contains the command
\r
122 that should be added at the end of the specified rows.
\r
123 Default value is \code{NULL}, i.e. do not add commands.}
\r
124 \item{sanitize.text.function}{All non-numeric enteries (except row and
\r
125 column names) are sanitised in an attempt to remove characters which
\r
126 have special meaning for the output format. If
\r
127 \code{sanitize.text.function} is not NULL (the default), it should
\r
128 be a function taking a character vector and returning one, and will
\r
129 be used for the sanitization instead of the default internal
\r
131 \item{sanitize.rownames.function}{Like the
\r
132 \code{sanitize.text.function}, but applicable to row names.
\r
133 The default uses the \code{sanitize.text.function}. }
\r
134 \item{sanitize.colnames.function}{Like the
\r
135 \code{sanitize.text.function}, but applicable to column names.
\r
136 The default uses the \code{sanitize.text.function}. }
\r
137 \item{math.style.negative}{In a LaTeX table, if \code{TRUE}, then use
\r
138 $-$ for the negative sign (as was the behavior prior to version 1.5-3).
\r
139 Default value is \code{FALSE}.}
\r
140 \item{html.table.attributes}{In an HTML table, attributes associated
\r
141 with the \code{<TABLE>}tag.
\r
142 Default value is \code{border=1}.}
\r
143 \item{print.results}{If \code{TRUE}, the generated table is printed to
\r
144 standard output. Set this to \code{FALSE} if you will just be using
\r
145 the character vector that is returned invisibly.}
\r
146 \item{format.args}{List of arguments for the \code{formatC} function.
\r
147 For example, standard German number separators can be specified as
\r
148 \code{format.args=list(big.mark = "'", decimal.mark = ","))}. }
\r
149 \item{rotate.rownames}{If \code{TRUE}, the row names are displayed
\r
150 vertically in LaTeX. }
\r
151 \item{rotate.colnames}{If \code{TRUE}, the column names are displayed
\r
152 vertically in LaTeX. }
\r
153 \item{booktabs}{If \code{TRUE}, the \code{toprule}, \code{midrule} and
\r
154 \code{bottomrule} tags from the LaTex "booktabs" package are used
\r
155 rather than \code{hline} for the horizontal line tags. }
\r
156 \item{scalebox}{If not \code{NULL}, a \code{scalebox} clause will be
\r
157 added around the tabular environment with the specified value used
\r
158 as the scaling factor. }
\r
159 \item{width}{If not \code{NULL}, the specified value is included in
\r
160 parenthesis between the tabular environment \code{begin} tag and the
\r
161 alignment specification. This allows specification of the table
\r
162 width when using tabular environments such as \code{tabular*} and
\r
163 \code{tabularx}. Note that table width specification is not
\r
164 supported with the \code{tabular} or \code{longtable} environments. }
\r
165 \item{comment}{If \code{TRUE}, the version and timestamp comment is
\r
166 included. Default value is \code{TRUE}. }
\r
167 \item{timestamp}{Timestamp to include in LaTeX comment. Set this
\r
168 to \code{NULL} to exclude the timestamp. Default value is \code{date()}. }
\r
169 \item{...}{Additional arguments. (Currently ignored.) }
\r
172 This function displays or writes to disk the code to produce a table
\r
173 associated with an object \code{x} of class \code{"xtable"}.
\r
174 The resulting code is either a LaTeX or HTML table, depending on the
\r
175 value of \code{type}. The function also (invisibly) returns a
\r
176 character vector of the results (which can be helpful for
\r
179 Since version 1.4 the non default behavior of \code{hline.after} is
\r
180 changed. To obtain the same results as the previous versions add to
\r
181 the \code{hline.after} vector the vector \code{c(-1, 0, nrow(x))}
\r
182 where \code{nrow(x)} is the numbers of rows of the object.
\r
184 From version 1.4-3, all non-numeric columns are sanitized, and all
\r
185 LaTeX special characters are sanitised for LaTeX output. See Section
\r
186 3 of the \code{xtableGallery} vignette for an example of customising
\r
187 the sanitization. From version 1.4-4, the sanitization also applies to
\r
188 column names. To remove any text sanitization, specify
\r
189 \code{sanitize.text.function=function(x){x}}.
\r
191 From version 1.6-1 the default values for the arguments other than
\r
192 \code{x} are obtainined using \code{getOption()}. Hence the user can
\r
193 set the values once with \code{options()} rather than setting them in
\r
194 every call to \code{print.xtable()}.
