Summary re: read.table on Mac OS 10
That's not the current version of R. When you update to 1.4.1 you'll see the bug fix list includes this. It transpired that the posting earlier today about the speed of read.table on Darwin vs Carbon was also a difference in R version (1.4.0 vs 1.3.1). Please do tell us the R version(s) you are using when posting. Installing 1.x.1 to replace 1.x.0 is highly recommended, for all values of x.

Prof. Ripley, I encountered the read.table problem in the Darwin version using as.is=TRUE, but not with as.is=FALSE. It gives different results than the Carbon version does. The output for each version follows; 'temp' is a two-line text file with three tab-delimited columns. UNDER DARWIN:
> read.table('temp')
V1 V2 V3 1 AFFX-BioB-5_at -214 -139 2 AFFX-BioB-M_at -49 -11
