windows limits
Hello,
Using the rgl package, I can set the device window to any dimension (that I
have tested):
par3d(windowRect=c(1,1,700,700))
With windows I can't get the window to span from the top to the bottom of
the monitor. In the following, no matter how large the ypinch value gets it
stops, leaving about 2 inches of space at the bottom of my screen:
windows(record=TRUE, ypinch=1100, xpinch=10,

tyring to save plots using windoze 7 and cygwin
Hi,
I'd been using R in the past and recently installed it on a new windoze 7 machine.
There have been many issues with compatibility and 32/64 bit apps etc and I did
find on google on isolated complaint that saveplot failed in scripts a long time ago.
R seems to work fine except script-based plot saving as pdf has not worked.
I have tried the following, none of which seem to function,

bitmap (blank image) plot rendering without X11
Hi,
I am trying to generate plots on our unix (no X) server to be included
in our web-pages -> specifically pngs.
Without X, png() obviously doesn't work, so I have been trying to define
the graphics print device bitmap as described in the help:
> bitmap(file="plot.png", type = "png256", height = 6, width=6,res=72)

Creating gif files using R
Greetings,
I am a new user of R but a long time fan of S (Splus) and have
installed R version 0.65.1 on a
Windows NT machine. I would like to save plots as gif files and have
been using savePlot()
with some success. I found that savePlot would not work without
modification, namely
decrementing the device by 1 before calling the internal routine that
does the conversion. Once

X11 & dev2bitmap
Hi,
I am trying to put some graphics I have generated from R on a
webpage using dev2bitmap to create a bitmap, .BMP, file.
When I look at my notes from 2 or 3 months ago I was successfully able to
put the ACTIVE device plot result into a bitmap file using a command such
as:
dev2bitmap("InsectSpray.BMP")
Job done!
Now when I try the same command, I get the following:

bitmap copies of plots
Michael Lapsley was suggesting on R-help direct copies to gif/png/jpeg.
The following seems to do a sensible job for me of copying the current
device to any bitmap format supported by gs. The manipulation is needed
to work around assumptions made by postscript(), and I think better fixed
in postscript() (but not a couple of days before a release).
I want to make onefile=FALSE work on

dev2bitmap error, 'gs' cannot be found
Dear List,
I am using the bioconductor package Category to do some gene enrichment
analysis, and usually save my KEGGmnplot's using a dev2bitmap command.
This has worked just fine, until suddenly earlier today I got this

Invalid device number in savePlot
Hi,
I recently encountered an error using the command "savePlot" when trying to
save the third of 3 open graph windows. After successfully saving and
closing the first two windows I receive an "Invalid device number in
savePlot" error. The following is copied and pasted from an example session
to illustrate the behaviour:

DEV2bitmap: jpeg with res=400 not enough for CORELDRAW poster A0
Dear all,
When saving a plot with the dev2bitmap command:

Everything seems to be ok... After importing this picture in CORELDRAW (for
a poster A0) format the resolution and colors are not optimal.
How can I save pictures (colors/resolution) optimally for import into

cross reference wishlist item
It would be nice for checking documentation to be able to generate the
"see also" cross references (e.g. the list of functions where dev2bitmap
is linked as a "see also" reference.) Perhaps this already exists?
(BTW, it would be useful to have a "see also" reference to dev2bitmap in
the help for postscript and for Devices.)

savePlot for Mac and / or Linux?
Hi all,
In the package rtlu, I use the function savePlot. It is convenient since
it let the user decide in which graphic format he wants his graph to be

inter tick distance
R colleagues,
I am stumped. I would like the inter-tick distances to be the same on the x
and y axes but cannot determine how to do so when the lower half of the y
axis is not printed. Thanks for any and all suggestions. (btw, setting
par(pty="s") does not solve my problem)
