1) As the posting guide asked, update your R. R 2.7.x has a new png()
device that many people prefer.
2) As the INSTALL file points out, this is an installation issue discussed
in the R-admin manual. JPEG and PNG support is optional (even on Windows,
but someone compiled it in for you if you are using a binary).
R does run on Solaris 8 and does support jpeg() and png() there *if you
follow the R-admin manual* and install the additional software needed.
(For how much longer we will be able to test under Solaris 8, I don't
know -- the system I use will be decommissioned this summer.)

Hi everybody,
I am currently working with R and I would like to create jpeg graphs with it.
Hmm, it is jpeg() creates jpeg graphs, not png().
I am working on Windows and Unix but I would like to be able to create
graphs (jpeg, png, bitmap...) under Unix.
I am working on Solaris version 8. The documentation for R states that
the latest version of or R known to compile on Solaris 8 is version
2.6.2. I have been able to compile and install R version 2.6.2. under
Unix. I also installed Hmisc package needed by my script.
The problem is that when I launch my script to create graphs from text
files I get this error :
Create_Graph("File")
Error in X11(paste("png::", filename, sep = ""), width, height, pointsize, :
unable to start device PNG
In addition: Warning message:
In png(paste(PATH, "/", filename, sep = ""), 800, 600) :
no png support in this version of R
The thing is that I have tried to run my script under Windows with the same
version (2.6.2) and everything is going well and the graph are created.
Is it because (under Unix):
capabilities()
jpeg png tcltk X11 http/ftp sockets libxml fifo
FALSE FALSE FALSE TRUE TRUE TRUE TRUE TRUE
If so, could someone explain to me how to change these capabilities in
order to ba able to set them TRUE.
I have also tried with other version of R but the error is the same one.
If you have any other ideas about why it doesn't work I would be very
grateful.
The fact is that I have created a programm under Unix to make automatic
the creation of the text files and I would like to create automatically
the correspondant graphs.
I hope someone will be able to help me.
Thanks for your time.
Have a good day.
R.
