This is my third attempt to send this message. Hopefully this one will go
through. If anybody got my previous attempts (one with 3 attached PNG
files and one with graph embedded in the message) I apologize for multiple
postings.
I tried to illustrate this possible bug by including screenshots but it
seems that these posts get blocked by something (r-devel-bounce?). Below
I try to describe what happens in words.
I have been compiling patched and development versions of R regularly. I
started compiling R-10.0 alpha a couple of days ago and I think I
discovered a bug in the "windows()" command.
Here is what is happening:.
1. Just compiled the latest tarball. Before doing this I updated the
R-tools to version 2.10 (includes jpeg-7).
2. Compilation went fine and I successfully built and ran the Windows
installer.
3. I also successfully ran "make check-all".
4. I start R GUI and do "plot(1:10)". Here is what I get:
The plot is missing bottom and right-hand side (both the axis and part of
the box).
The bottom is missing up to the third dot on the plot, i.e., the x-axis is
missing
together with the first three points.
5. When I go to File>Save As>Png... and go through the dialog box
(choosing a file name) I get the following GUI error:
A window pops up saying: "R for Windows GUI has encountered a problem and
needs to close.
We are sorry for the inconvenience". Closing this window causes R to
crash.
6. When, before saving, I resize the graphics window with my mouse even
by a very small amount, the plot changes to its normal look (without
missing axes of plot.png) and I can save it with no problem.
7. When I do the same thing in just compiled 2.9.2 everything works fine
and the plot (plot.png above) looks fine.
8. I suppose, all this is related to the following result of the
"windows()" command:
I get a window with the upper left chunk of it being dark gray and the
remaining part, i.e.,
the bottom and the right-hand side being white. The white portions
correspond to the missing
parts of the plot described in 4. Again, resizing this window even
slightly, fixes the
problem - the whole window becomes dark gray.
I am on the Windows XP SP2 machine. Here is the output of R.version:
