Most used R editors
Hi,
I am a little lonely as R users in my group. So, I would like to know which editor is the most used in the R community.
This post is some kind of survey.
Personally, I use Emacs with ESS, It permits to :
- open more than one R session
- split the emacs editor as many part as you want.
- use a lot of keybindings.
...
I also tried Rkwards, Scilab (windows), JGR etc... but they are not

tiff(), jpeg(), and png() in R 2.7.0: problems if 'units = "in"' but default height and width
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 reproducible example:

automated image processing
Hi,
I am looking for a R package which is capable to process and analysis pictures of tissues (stained) in an automatic way.
I had a look on biops and EBImage (Bioconductor) but they are not automatic...
Did you already use/know a such package ?
Thanks,

Using jpeg() without X
When I tried this, I'm having this error. Can somebody help me on
this. Are there any alternatives or workaround for this? I'm having
hard time to convince our admin to install X11 library and headers
since they are not included on the default OS installation.
Thanks in advance :)

beta symbol cut off in y axis label using jpeg/png/tiff
I am having trouble showing the Greek symbol "beta" correctly

Dear All,
I would like to use the 'split' function on the dataframe elements contained in a list L.

png(type='cairo'): point symbols without boarders are not anti-aliased?
Hi,
It seems that anti-aliasing in png(type = 'cairo') is not well
supported for the point symbols without boarders, e.g. pch = 16. The
Cairo package works well, though. You can compare png() with

'Dynamic' 3D plot
Hi,
I am looking for a R package to draw 3d plot. But not in a static way like scatterplot3d or stuff like that. I would like to make rotate the plot, to zoom/unzoom etc..., actually to render the graph 'dynamic'... (for the biologist and bioinformatician, a R package which permitts to reproduce what pdb viewer does).
Does a Way exist to do something like that in R ?
Thanks,

X11 png jpeg cledit false when running from script

to a browser, it is unable to complete because of this. Any ideas are
appreciated. We have an identical

empty files created with trellis xyplot jpeg device
New years greetings.
I have been setting up a function to generate multiple jpeg charts. When
the calls are issued at the interactive console, the jpeg files are
generated without an issue. When I try to issue the same calls from a
function, some chart files are empty. It appears to only be related to
trellis charts. Any help to troubleshoot this is appreciated.
