Usage

# S3 method for ordfor
plot(x, useggplot = TRUE, ...)

Arguments

x

object of class ordfor. See function ordfor.

useggplot

...

other parameters to be passed through to plotting functions if useggplot=FALSE.

Examples

# NOT RUN {
data(hearth)

set.seed(123)
hearthsubset <- hearth[sort(sample(1:nrow(hearth), size=floor(nrow(hearth)*(1/2)))),]
ordforres <- ordfor(depvar="Class", data=hearthsubset, ndiv=80, nbest=5)
# NOTE: ndiv=80 is not enough!! In practice, ndiv=1000 (default value) or a higher
# number should be used.

plot(ordforres)

plot(ordforres, useggplot=FALSE)

# }
