Subject: How to label a plot of a tree dendrogram with text
Dear R list,
I have generated a object of class rpart in R 2.1.1
(using the wrapper function "mvpart" of the
mvpart-package version 1.0-1). In order to label the
plot of the tree dendrogram with text I used
"text.rpart". In this function it is possible to set
the argument "label" to determine which values will
label the nodes. In the case of my tree-object I have
the following possibilities to chose the
label-argument:
> prunedtree2$frame[1:1,]
var n wt dev yval complexity ncompete
nsurrogate yval2.1 yval2.2 yval2.3 yval2.4
1 EST 4258 4258 377874512 113.6452 0.2399082 4
1 230.56740 118.06599 78.31141 27.63598
In order to produce labels with variable "n" I
entered:
> plot(prunedtree2)
> text.rpart(prunedtree2,label="n")
Although I set label="n", it always produces labels
with variable "dev". I tried also to set label="yval",
label="yval2.1", ... without any success, everytime it
produces labels with "dev". What am I doing wrong?
Thanks, Pedro.
