[R] Problem about Rprof() (Windows build 1.6.2)

[asone@latte.harvard.edu]

Dear R users:

I have a problem about Rprof() on R for windows (Version 1.6.2
(2003-01-10)). 

When I tried to run an R program, which yields non-empty profiling
results with Rcmd Rprof on R (windows: Version 1.5.0 Patched
(2002-06-12)),  I got the following empty result:


Each sample represents 0.01 seconds.
Total run time:  seconds.

Total seconds: time spent in function and callees.
Self seconds: time spent in function alone.

   %       total       %       self
 total    seconds     self    seconds    name

   %       self        %       total
 self     seconds    total    seconds    name


summaryRprof() was also tried, but what I got is the following message: 

> summaryRprof(filename = "Rprof_xtab_none.out")
Error in summaryRprof(filename = "Rprof_xtab_none.out") : 
        no events were recorded
>

I noticed this problem when I tested the same R program on R (windows)
Version 1.6.1 last year.

Did I miss some important announcement concerning Rprof() between R 1.5.
0 and 1.6.1?
