JPEG supported on UNIX?

Hi everyone,

Any help will be really greatful.

I would like to know if UNIX provides support for JPEG, PNG or BMP for R? I looked for these,especially JPEG, by using the capabilities() function and it says NOT available.

This is the error message i get for jpeg():

Error in X11(paste("jpeg::", quality, ":", filename, sep = ""), width, :
unable to start device JPEG
In addition: Warning message:
could not open JPEG file 'Rplot001.jpeg'

The X11() display also does not get loaded.

The version of R is 2.1.0. (2005)

Any ideas on how i can get the above formats through UNIX?

Thanks a lot in advance!

I had perl create an R script as a file. I used a template and the Perl Template Toolkit to do this. Then, I call R like this:

my $cmd = qq( <R executable> CMD BATCH <R script> );
my $errorlevel = system($cmd);

You can check if it worked like this:

if ($errorlevel) {

# handle errors

}

Regards,
Michael.

Subject: [Biodevelopers] Running R from Unix Command Line

Hello all,

If someone can please throw a light on this I would be eternally greatful :

I have a CGI PERL Script that needs to invoke the R program on the command line of UNIX and send commands to it.

Can I do this using the normal system command? Would this work? If so, how can I specify the commands without clashing with the double quotes of perl and that of R?

If not, could someone please suggest an alternative to this ?

Thanks

Shalini
