R help - Feb 2008 - R console closes on its own

Dear R-experts,

   I am running a script that has the following
structure:

windows(height=5.5,width=8)

dat<-read.csv("myfile.csv")
names(dat)<-c('a','b','c','d')
dat<-dat[,1:4]

xyplot(dat$a~dat$b)


   Then I usually save the plot as a PDF (from the
menu in the R console). I can save the PDF twice in a
row; but at the third time, right when I am about to
give a name to the graph, R crashes, no error
messages.

  I am using R 2.6.2, for Windows. I copy the script
from TinnR.

Thank you in adavance for any help,

Judith

Hi Judith,

If I undestand, see ?savePlot and try this

xyplot(dat$a~dat$b)
savePlot(filename="C:\\yourname",type=c("pdf"),device=dev.cur())


I hope this helps.

That sounds like a bug, in R or TinnR.  Can you reproduce the problem if 
you don't use TinnR?  If so, could you send me a version of myfile.csv, 
and I'll see if I can reproduce it and fix it.  (You might be able to 
reproduce it without the read.csv() call, just by creating dat with fake 
data, e.g. dat <- data.frame(a=1:10, b=1:10, c=1:10, d=1:10).

If the bug requires TinnR, then you should probably send details to its 
maintainers.

I can reproduce a crash using the following code:

for (i in 1:100) {
windows()
plot(1:100)
}

When R opens too many graphics windows, it is running out of memory, but 
not failing gracefully.  It should be easy to fix.

The workaround in the short term is not to accumulate open graphics 
windows; close them when you're done.  This code runs without error:

for (i in 1:100) {
windows()
plot(1:100)
dev.off()
}
