I love the new tiff(), jpeg(), and png() in R 2.7.0 but found
an issue that I didn't see reported.
When specifying 'units = in' but forgetting to change the
default height and width (so the figure is unintentionally
going to be 480 inches by 480 inches) I run into problems.
Here's the

Hi R-Developers,
I'm working on running statistical analyses with embedded R from a
Qt-GUI-application (C++).
I've been able to link with R libraries, but I'm having a hard time to
understand the C-coding examples. I'm a C++, not a C programmer (never
used malloc before), and many of the
Dear list,
Is it intentional that example() opens a new device and leaves it in a
mode where it asks (prompts) the user to Press return to see the next
plot for *all* subsequent plots on that device.
For example; with an already opened device, example() works as I would
expect:

the result, but that's not the case when the pattern matches the end of
the search string:
strsplit( hello dolly )

Dear List,
In investigating this a bit more, I've just realised that the source has
this nice comment (in the svn trunk) indicating that there is a problem,
and it is known about:
## FIXME
## This ensures that any device opened by the examples will
## have ask = TRUE set,
Oh my, I regret my stupidity.

great feature.
But I have a problem with this feature, when R_LIBS is defined.
It works well the first time, when R creates the directory defined in
