Hi, Stephen:
The directory "C:\Users\satimiswin764\My
Documents\R\win-library\2.12\gdata\perl" is NOT the perl interpreter but
only perl code in the gdata package for R, invoked by certain R
commands. You need to install something like "Strawberry perl", as I've
previously stated.

Yes, I did.
I found something strange here which I can't explain.
Win 7 64bit
R 32/64 bit
Just rebooted Win 7 and R
library(gdata)
gdata: Unable to locate valid perl interpreter
gdata:

Attaching package: 'gdata'
The following object(s) are masked from 'package:utils':
object.size
It complains.
?read.xls
starting httpd help server ... done
"Read Excel files"
Both 32 and 64 bit R worked.
If there is NO complaint on running;
library(gdata)
Then
?read.xls
can't work.
Perl seems has been installed. But I can't recall, when and how;

?read.xls
I must run ??read.xls
Not if you

first. Then
?read.xls
should work.
