plot.C5.0: Plot a decision tree

Description

Plot a decision tree.

Usage

# S3 method for C5.0
plot(x, trial = 0, subtree = NULL, ...)

Arguments

x

an object of class C5.0

trial

an integer for how many boosting iterations are used for prediction. NOTE: the internals of C5.0 are zero-based so to get the initial decision tree you must use trial = 0. If trial is set too large, it is reset to the largest value and a warning is given.

subtree

an optional integer that can be used to isolate nodes below the specified split. See partykit::party() for more details.

...

options passed to partykit::plot.party()

Value

No value is returned; a plot is rendered.

Examples

# NOT RUN {
mod1 <- C5.0(Species ~ ., data = iris)
plot(mod1)
plot(mod1, subtree = 3)


mod2 <- C5.0(Species ~ ., data = iris, trials = 10)
plot(mod2) ## should be the same as above

## plot first weighted tree
plot(mod2, trial = 1)

# }
