[SAS marketroid quote]
In fact, SAS values open-source software.
But clearly not enough to open-source SAS itself. It would seem that
SAS values _other_people's_ open source.
If SAS was open source and free, then SAS would collect on all the

Is there anyway that I can have both the text and graphic

Hi,
I have about 900 files that I need to run the same R script on. I looked
over the R Data Import/Export Manual and couldn't come up with a way to
read in a sequence of files.
The files all have unique names and are in the same directory.

Since I'm a SAS programmer, I'm used to creating command files in an editor
for submission later. Is there a way to do this in R? I'd need to retain an

You probably want R CMD BATCH from a command-line. For

Hi, I'm using rgl to generate a 3D surface plot and I'm struggling to get

Let me try to be more specific.
The x y coordinates are different because of NAs in the dataset. In this
