From the posting guide:
For questions about unexpected behavior or a possible bug, you should,
at a minimum, copy and paste the output from sessionInfo() into your
message.
(This would have told us the rpart version number.)
When mentioning version numbers, always use the full version number,
e.g., `2.6.1', not just `2.6', and also mention the platform
(Windows2000, Linux, MacOS X, with their versions).
If the question relates to a contributed package , e.g., one downloaded
from CRAN, try contacting the package maintainer first.
(rpart is a contributed package: see library(help="rpart").)
And from the FAQ:
Bug reports on contributed packages should be sent first to the
package maintainer, and only submitted to the R-bugs repository by
package maintainers, mentioning the package in the subject line.
As the rpart maintainer I can tell you that this will be changed to use
dev.new() in the next release, but the current release (3.1-41) is over 6
months' old and predates development of 2.8.0.

Hi,
This happens in 2.8 and 2.9. I am posting this here because I am not sure
if one should use bug.report for reporting bugs in unreleased versions.
I was trying to run the example from the help page of plot.rpart. I got
library(rpart)
fit <- rpart(Price ~ Mileage + Type + Country, cu.summary)
plot(fit, compress=TRUE)
Error in get(getOption("device")) : invalid first argument
This also produces a blank graphics window. When I run the plot command
again everything seems to work fine, so the error only occurs when the
graphics window is not open.
I use Windows XP SP2. I just compiled the newest RC of 2.8 (R version
2.8.0 RC (2008-10-14 r46714)). I ran "make fullcheck" on it and
everything checked out fine.
The same thing happens in 2.9 but it worked fine in 2.7.2.
Andy
