Plot Vote Distribution

Plot distribution of votes for each sample in each class.

plotVotes(rf, type = NULL, freq.sep.line = TRUE, plot = TRUE)

`rf`	an object inheriting from `randomForest`.
`type`	either `area` for stacked continuous area plot or `bar` for discrete stacked bar chart. The latter is prefered for small numbers of cases. If not specified, a bar chart will be used if all classes have <= 30 cases.
`freq.sep.line`	put frequency of original group on second line in facet label? If `FALSE`, labels are single line. If `NULL` frequencies will not be included in labels.
`plot`	display the plot?

the ggplot2 object is invisibly returned.
