Reading graphics files

...

library(pixmap), perhaps? Reads PNM (so PPM, PGM, PBM).

Thanks!  This is precisely what I was looking for.  I had gotten to the
point of:

con<-file("image.ppm",open="rb")
readLines(con,n=3)

[1] "P6"      "600 400" "255"

zz<-readBin(con,size=1,n=3*600*400,what='int')
close(con)
dim(zz)<-c(3,600,400)
image(1:600,1:400,zz[1,,400:1])

... and then realized that the coordinates and colormaps would be awkward.

Thanks to Frederich Leisch and Roger Bivand for writing the CRAN pixmap
package.  Would a pointer to it in the see-also sections of 'bitmap',
'png', and 'image' be appropriate?

Thanks again,
Dave
