Hello,
I 've just re-installed R 2.9.0 on ubuntu 9.04.
I do not understand why I am unable to use simple device function such as
jpeg(), png()...
> png()
Error in X11(paste("png::", filename, sep = ""), width, height, pointsize, :
unable to start device PNG
In addition: Warning message:
In png() : no png support in this version of R
> capabilities()
jpeg png tiff tcltk X11 aqua http/ftp sockets
FALSE FALSE FALSE FALSE TRUE FALSE TRUE TRUE
libxml fifo cledit iconv NLS profmem cairo
TRUE TRUE FALSE TRUE TRUE FALSE FALSE
It's not really a problem because i use cairo but i would like to know the
source of this error.
I checked the library as proposed in previous post :
https://stat.ethz.ch/pipermail/r-help/2005-December/085177.html
but all of them (libpng, libjpeg...) are already installed.
Did someone ever find the source of this R Error ?
Thanks !
- Martial
