I don't think this is an RStudio issue. The plot() method for
"rpart"
objects draws no labels. The text() method has to be called additionally:
library("rpart")
rp <- rpart(Species ~ ., data = iris)
plot(rp)
text(rp)
As these plots produced by rpart itself are not very appealing, there are
various approaches that allow drawing other displays, e.g.,
library("rpart.plot")
prp(rp)
library("rattle")
fancyRpartPlot(rp)
library("partykit")
plot(as.party(rp))
which show different amounts of detail and use different visual means to
display the available information.
