Hi,

When I want to output a png file, I have the following error message :

Error dans X11(paste("jpeg::", quality, ":", filename, sep = ""), width,  :
        inpossible de d?marrer le p?riph?rique JPEG
De plus : Warning message:
impossible d'ouvrir le fichier JPEG 'Test.jpeg'

or in english

Error in X11(paste("jpeg::", quality, ":", filename, sep = ""), width,  :
        inpossible to start the JPEG peripheral
Warning message:
impossible to open the file JPEG 'Test.jpeg'

I've checked the capabilities which give :

 > capabilities()
    jpeg      png    tcltk      X11 http/ftp  sockets   libxml     fifo
    TRUE     TRUE    FALSE     TRUE     TRUE     TRUE     TRUE     TRUE
  cledit    iconv      NLS
    TRUE     TRUE     TRUE

So I don't understand why I can't have a jpeg file ( or png file because 
I've the same problem to)

Any Idea ?

Thx a lot

Probably you have no write permission in the current directory.  That 
message means (as it says) that the process cannot open the file for 
writing, and that is not an R issue.
