[R] raster plot is empty

[Alex Olssen]

Unfortunately the capabilities are identical too.

For both systems I get

    jpeg      png     tiff    tcltk      X11     aqua http/ftp  sockets
    TRUE     TRUE     TRUE     TRUE    FALSE    FALSE     TRUE     TRUE
  libxml     fifo   cledit    iconv      NLS  profmem    cairo
    TRUE    FALSE     TRUE     TRUE     TRUE     TRUE    FALSE
