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

[asone@latte.harvard.edu]

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?
