something missing from the graph of recursive partitioning

Hi

The following codes come from R example. I save its
graph as rpart.ps, but the graph did not display the
whole word, e.g. just display "bsent", not "absent" in
the most left. can you advise me how to solve it?

The text is being clipped to the plot boundaries.  The following minor
adjustment to your code shows where the clipping is occurring [indicated by
a dashed box around the plot boundary] and a possible fix [via par(xpd)]:

library(rpart)
data(kyphosis)
fit <- rpart(Kyphosis ~ Age + Number + Start, data =
kyphosis)
fit2 <- rpart(Kyphosis ~ Age + Number + Start, data =
kyphosis,
parms = list(prior = c(0.65, 0.35), split =
"information"))
postscript("rpart.ps", width=960, height=960)
par(mfrow = c(1, 2))
par(xpd=NA)  # or par(xpd=T)
plot(fit)
text(fit, use.n = TRUE)
box("plot", lty="dashed")
plot(fit2)
text(fit2, use.n = TRUE)
box("plot", lty="dashed")
dev.off()
