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
