[R] Problem with pixmap on R 1.7.0?

[Roger Peng]

I think I've gotten this same error on a Linux (Red Hat 8.0) machine.
Here's the traceback:

> z <- read.pnm("llama.pnm")
Error in .class1(object) : Object "from" not found
> traceback()
10: .class1(object)
9: as(from, "pixmapChannels")
8: asMethod(object, Class, value)
7: "as<-"(*tmp*, Classi, value = obj)
6: initialize(value, ...)
5: initialize(value, ...)
4: new("pixmapRGB", pixmap(data, ...))
3: pixmapRGB(0, ncol = dim(res)[2], nrow = dim(res)[3], ...)
2: read.pnmdata(con, pnmhead, ...)
1: read.pnm("llama.pnm")

The image I used is at http://www.stat.ucla.edu/~rpeng/llama.pnm.  One
other thing -- this image used to be a JPEG file and I converted it to pnm
using the `convert' program from ImageMagick.  It's possible that
ImageMagick is screwing something up to but I'm not sure how to figure
that out.
