Thanks to Dr. Ripley and Dr. Murdoch for the workaround
and the solution to the problem with sub() and gsub() memory problem.
Now, with the perl=TRUE option added it works perfect (with the full
database)!
alumnos$AL_NUME_ID-gsub((^ +)|( +$),,alumnos$AL_NUME_ID,perl=TRUE)
I am going to test it

Hi R developers:
Congratulations for the new R 2.10.0 version.
It is a huge effort! Thank you for your work and dedication.
I just want to ask how to make this strip blank function
to work again (it works on R.2.9.2).
Dr. Murdoch:
I am puzzled!
As you adviced me I do this:
x - as.character(alumnos$AL_NUME_ID)
x - x[-seq_len(length(x)/2)]
y - gsub((^ +)|( +$),,x)
And it fails,
But, trying to locate the problem I do:
x - as.character(alumnos$AL_NUME_ID)
x - x[-seq_len(length(x)/2)]
x -

Please try the following. After doing the lines above, do
save(x, file=x.RData)
and exit from R. Then

What happens if you type
Sys.setlocale('LC_ALL','C')
before using gsub or grep?
When I do that, R hangs and don't show any message.
