Hi, Is there a way to read .bmp files into R? I have tried read.pnm from pixmap package. It returned Error in pm.readmagicnumber(con) : Not a PNM format file Anyother ways to load bitmap images? Yi-Xiong

...ne x <- read.pnm(system.file("pictures/logo.ppm", package="pixmap")[1]) plot(x) #draws an R logo, nice :-) But my code returns an error x<-read.pnm("C:/Documents and Settings/simonp/My Documents/Simon BTO/RELU/GIS data/ten km areas in analysis.bmp") Error in pm.readmagicnumber(con) : Not a PNM format file I have tried changing the dpi when I export the image but still no cigar. I have dredged the help forum for related files and read the help files. My Os is windows XP and i'm running 2.8.1. I feel I'm missing something obvious! Thanks Dr. Simon Pickett Rese...
