If you are running Linux, Torsten's suggestion of oprofile is a good one,
provided you have root access (it seems to need it). So I used in a root
terminal (running the same example in another window in the middle)
% opcontrol --no-vmlinux
% opcontrol --start
run things ...

Hi,
I don't know much about eventloop.h (yet) but according to the
manual statement for add-on front-ends and for packages that need to
share in the R event loops (on all platforms) I thought it might make
sense to translate this to Pascal too.
But I have a couple of questions:
- no function
I noticed that R scripts produce a spurious white line after output.
For example, the following shell script,
#!/bin/sh
R --slave --vanilla EOF
cat(Hello\n)
EOF
when made executable under the name ``hello`` along the search path, behaves
like this:
$ hello | od -bc
000 110 145 154 154
I agree with the submitter that this needs some kind of solution.
Although data.frame[,-12] works, how do I drop a named column (the
most common use case)? (I found this bug while searching for an
answer.)
cheers

Hi, people. The output produced by ?options contains:
'expressions': sets a limit on the number of nested expressions
that will be evaluated. Valid values are 25...50 with
default 1000. [...]

Oh, sorry. I merely surmised that R developers were aware of the
meaning of --slave option.
We are.

This is already corrected in the the development version of R: see
