R help - Oct 2011 - Strange error msg when plotting a graphics

Dear R-Users

I have come across the error that apparently has nothing to do with command
itself.  Here is the error

(w - matrix (or vector) e testXaxis - dates).
> plot(data.frame(testXaxis,w),col="blue",ylab="Q,
[m3/s]",xlab="Data",
+      main="Free-run - Modelo NARX MISO - Test Data")
Error in gzfile(file, "wb") : cannot open the connection
In addition: Warning message:
In gzfile(file, "wb") :
  cannot open compressed file
'/Users/eduardo/.rstudio-desktop/graphics/0540fa66-727a-4f8f-a1b5-f6501e96a393.snapshot',
probable reason 'No such file or directory'
Graphics error: Error in gzfile(file, "wb") : cannot open the
connection

The error did not stop the graphics of being plotted.

What could be wrong?

Many thanks

Ed

Using R-help to report a problem in Rstudio?

When reporting graphics problems, you need to report the graphics 
device you use, as well as the 'at a minimum' information required by 
the posting guide.  This looks like a problem in Rstudio's own 
device/UI, but I am guessing from the file name.

If you use an alternative front-end such as Rstudio or Tinn-R (or even 
RKWard) please do mention it in your posting.
