R help - Jan 2003 - Problem about Rprof() (Windows build 1.6.2)

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
version=(build 2195) Service Pack 3
machine=x86

platform=i386-pc-mingw32
arch=i386
os=mingw32
system=i386, mingw32
statusmajor=1
minor=6.2
year=2003
month=01
day=10
language=R

Rprof()
example(lm)
Rprof(NULL)
summaryRprof()

works perfectly here on the build I installed an hour ago.

Did you perchance forget to turn profiling off as in the third line, so the
file was not closed?

Thank you for your advice, Prof. Ripley.

What I found after your e-mail is as follows:

when the following 4 command lines are typed in R Console one by one on
R (windows) Version 1.6.2  (2003-01-10), 

Rprof()
example(lm)
Rprof(NULL)
summaryRprof()

I got profiling results.

However, when I typed the following line in the R console,

	Rprof(); example(lm); Rprof(NULL); summaryRprof()

or 

the above 4 command lines were saved as a program file, "testRprof.R",
and it was executed as:

	>source("C:/asone/R/testRprof.R")

then I got the following error:

	Error in summaryRprof() : no events were recorded


When I tried the last two approaches, i.e., 

	Rprof(); example(lm); Rprof(NULL); summaryRprof()
	source("C:/asone/R/testRprof.R")

with R (windows) Version 1.5.0 Patched (2002-06-12) with "Rcmd Rprof
Rprof.out",

I could get profiling results. 

So is this a problem concerning not Rprof but the command interpreter?
