Hi, I'm having trouble writing .pnm images which I think is due to a problem with my colour space. The pixmap object seems to be looking for 72 of 8 colours (one per cell?) which doesn't seem healthy...
> library(pixmap) > x <- pixmapIndexed(rep(1:8, 9), nrow=6, col=rainbow(8)) > x Pixmap image Type : pixmapIndexed Size : 6x12 Resolution : 1x1 Bounding box : 0 0 12 6 Nr. of colors : 72 of 8 > write.pnm(x, file="D:/Temp/output.pnm") Error in options(x) : evaluation nested too deeply: infinite recursion / options(expression=)? > Grey ones work but with a warning... > x <- pixmapGrey(rep(1:8, 9), nrow=6) > x Pixmap image Type : pixmapGrey Size : 6x12 Resolution : 1x1 Bounding box : 0 0 12 6 > write.pnm(x, file="D:/Temp/output.pnm") Warning message: connection is already open > Any ideas?
