You might get a fuller answer from others, but one thing you could try is using
bitmap() rather than png().
> Hi everybody,
> I am currently working with R and I would like to create jpeg graphs with it.
> 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 :
> 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):
> 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.
