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?

My platform-R_version information is as follows:

sysname=Windows
release=NT 5.0
