Plot an

This function is provided for backward compatibility with old versions of rpart.plot (prior to version 2.0.0, June 2016). By default this function creates a minimal unadorned plot, whereas rpart.plot creates a colored plot automatically tailored to the model's type. Actually, the only difference between the two functions is that some arguments have different defaults. This function has the same defaults as prp. See the rpart.plot help page for a table showing the different defaults.

Usage
rpart.plot.version1(x=stop("no 'x' arg"),
    type=0, extra=0,
    under=FALSE, fallen.leaves=FALSE,
    digits=2, varlen=-8, faclen=3,
    cex=NULL, tweak=1,
    snip=FALSE,
    box.palette=0, shadow.col=0,
    ...)
Arguments
x
Same as rpart.plot.

Default FALSE. Same as rpart.plot.
fallen.leaves
Default FALSE, otherwise the same as rpart.plot (which has a default of TRUE).
digits
Default 2. Same as rpart.plot.
varlen
Default -8, otherwise the same as rpart.plot (which has a default of 0).
faclen
Default 3, otherwise the same as rpart.plot (which has a default of 0).
cex
Default NULL. Same as rpart.plot.
tweak
Default 1. Same as rpart.plot.
snip
Default FALSE. Same as rpart.plot.
box.palette
Default 0, otherwise the same as rpart.plot (which has a default of "auto").
