I think you are misunderstanding something here. The compress argument 
is TRUE if the cdf file you are reading is compressed. It doesn't have 
anything to do with the output.

Is your cdf file really in R_HOME/library/makecdfenv/extdata? That is 
sort of an odd place to put things. Anyway, I don't have the same 
problem with the example file in that directory:

package="makecdfenv"),compress=TRUE, species = "Homo_sapiens")

[1] "hu6800.cdf.gzcdf"

I tried un-gzipping the cdf as well, and used compress = TRUE, and that 
still worked.

package="makecdfenv"),compress=TRUE, species = "Homo_sapiens")

You should also always give your sessionInfo()!

 > sessionInfo()
Version 2.3.0 RC (2006-04-17 r37823)
i386-pc-mingw32

attached base packages:
[1] "tools"     "methods"   "stats"     "graphics"  "grDevices" "utils" 
     "datasets"
[8] "base"

other attached packages:
makecdfenv       affy     affyio    Biobase
    "1.9.3"   "1.10.0"   "0.99.3"   "1.10.1"

What versions of makecdfenv, and more importantly, affyio are you using?

Also, if you download the Rtools and put them in your PATH, does the 
problem go away?
