R devel - Dec 2006 - jpeg() and png() in R-2.4.x (PR#9423)

I have tried to install R-2.4.x on my computer (linux - mandriva 2007 - 
64bits), with tar file for R-4.2.1 and rpm file for R-2.4.0, and 
function capabilities() says to me that JPG, PNG and TCLTK are not 
available. However, with the version R-2.3.x with whicc I work , they 
are available.
May be it's a bug, or may be my mandriva 2007 distribution are not all 
required libraries ? But I have not find "REQUIREMENTS" files on the 
CRAN site to verify that.

Thanks for your help,

Sophie Martin

The file INSTALL says

   The main source of information on installation is the `R Installation
   and Administration Manual', an HTML copy of which is available as file
   `doc/html/R-admin.html'.  Please read that before installing R.  But
   if you are impatient, read on but please refer to the manual to
   resolve any problems.  (If you obtained R using Subversion, the manual
   is at doc/manual/R-admin.texi.)

I suspect this was an installation problem, in which case it is covered in 
that manual.  Configure reports on the capabilities it found, e.g.

   Interfaces supported:      X11, tcltk
   External libraries:        readline
   Additional capabilities:   PNG, JPEG, iconv, MBCS, NLS
   Options enabled:           shared BLAS, R profiling, Java

and you have not told us what your build reported.

An alternative is covered by ?capabilities

      X11: (Unix)  Are the 'X11' graphics device and the X11-based data
           editor available?  This loads the X11 module if not already
           loaded, and checks that the default display can be contacted
           unless a 'X11' device has already been used.

which if false will imply that jpeg and png are not available (but tcltk 
could be).

You need to demonstrate that this really is a bug in R and not a 
mis-report using scarce resources (R-core time).  (The R build not 
magically finding missing components of your OS is not a bug.)
