Currently, this is not implemented in "party". In interactive usage it
is
not easy to change the fontsize. If you're printing to PDF, you could
easily increase/decrease the height and width which will decrease/increase
the relative size of the text, respectively. Not elegant but works.
Alternatively, you could obtain the "partykit" package from R-Forge
which
has a new implementation of general infrastructure for tree. With that you
can do
library("partykit")
irisct <- ctree(Species ~ ., data = iris)
plot(irisct, gp = gpar(fontsize = 20))
Note that "party" and "partykit" should not be used
together, partykit has
a slightly enhanced/modified ctree() function.
