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

read.table('temp',as.is=TRUE)

stack imbalance in internal type.convert, 26 then 25stack imbalance in
Internal, 25 then 24
stack imbalance in if, 19 then 18
stack imbalance in <-, 17 then 16
stack imbalance in {, 15 then 14
stack imbalance in for, 8 then 7
stack imbalance in {, 6 then 5
               V1   V2   V3
1 AFFX-BioB-5_at -214 -139
2 AFFX-BioB-M_at  -49  -11
Error: unprotect(): stack imbalance

UNDER CARBON:

read.table('temp')

               V1   V2   V3
1 AFFX-BioB-5_at -214 -139
2 AFFX-BioB-M_at  -49  -11

read.table('temp',as.is=TRUE)

               V1   V2   V3
1 AFFX-BioB-5_at -214 -139
2 AFFX-BioB-M_at  -49  -11

Best regards,
David
