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.
You could install R from an RPM: you only need the X11 headers to
build R. (It is possible if tricky to do that in a user account, but
you might persuade the sysadmin to do so.)
You could use the bitmap() device, if gs is installed.
You could use some of the third-party alternatives (packages Cairo,
GDD ...) *but* you almost certainly don't have the -devel RPMs they
depend on either. (I don't think the -devel RPMs needed for jpeg are
in 'the default OS installation', but it depends on which default.)
You could install a copy of X11 (and, preferably, cairographics) from
the sources in your own space.
Finally, you could talk to the 'admin's line-manager about his/her
employee's obstructive attitude.
Thanks in advance :)

Seems that libjpeg is available on our server
[r...@localhost R-2.11.1]# locate libjpeg
/usr/lib/libjpeg.so
/usr/lib/libjpeg.so.62
/usr/lib/libjpeg.so.62.0.0
Interesting: the first is in the libjpeg-devel RPM, so the sysadmin
has installed some unnecessary software already ....
I'm using Fedora 12 and compiled the newest version of r-project.
Here are my steps I've taken before I run that command
./configure --with-x=no --with-tcltk=no
