3 \title{Zoom on a Portion of a Phylogeny by Successive Clicks}
5 This function plots simultaneously a whole phylogenetic tree
6 (supposedly large) and a portion of it determined by clicking on the nodes of the phylogeny. On exit, returns the last subtree visualized.
9 subtreeplot(x, wait=FALSE, ...)
13 \item{x}{an object of class \code{"phylo"}.}
14 \item{wait}{a logical indicating whether the node beeing processed should be printed (useful for big phylogenies).}
15 \item{...}{further arguments passed to \code{plot.phylo}.}
18 This function aims at easily exploring very large trees. The main argument is
19 a phylogenetic tree, and the second one is a logical indicating whether a waiting message should be printed while the calculation is being processed.
21 The whole tree is plotted on the left-hand side in half of the device. The
22 subtree is plotted on the right-hand side in the other half. The user clicks on the nodes in the complete tree and the subtree corresponding to this node is ploted in the right-hand side. There is no limit for the number of clicks that can be done. On exit, the subtree on the right hand side is returned.
24 To use a subtree as the new tree in which to zoom, the user has to use the function many times. This can however be done in a single command line (see example 2).

34 tree2<-subtreeplot(tree1, wait=TRUE) # on exit, tree2 will be a subtree of tree1.
36 #example 2: more than one zoom
38 tree2<-subtreeplot(subtreeplot(subtreeplot(tree1))) #allows three succssive zooms.
