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.

What happens if you run the code in a terminal rather than RStudio? My
experience is that very, very occasionally RStudio does something a bit funny
with plots.
And while this may sound funny just shut down RStudio, reload it and try again.

Subject: [R] Rpart plot produces no text
I am using R Studio and am able to fit a tree with RPlot, however, the
tree in the viewer has no text (see image attached).
