I am puzzled!
As you adviced me I do this:
x <- as.character(alumnos$AL_NUME_ID)
x <- x[-seq_len(length(x)/2)]
Please try the following. After doing the lines above, do
save(x, file="x.RData")
and exit from R. Then restart R, and run
load("x.RData")
y <- gsub("(^ +)|( +$)","",x)
If it still fails, that's a sign that there's a problem in that vector
of values; if not, it's likely some sort of memory problem that will be
harder to track down. In the former case you could email me the file
and if it also fails here I can probably track it down. If it's a
memory problem, I can try, but I'm less optimistic that I'll find it.

And it fails,
But, trying to locate the problem I do:
x <- as.character(alumnos$AL_NUME_ID)
x <- x[-seq_len(length(x)/2)]
x <- x[seq_len(length(x)/2)]
y <- gsub("(^ +)|( +$)","",x)
works
x <- as.character(alumnos$AL_NUME_ID)
x <- x[-seq_len(length(x)/2)]
x <- x[-seq_len(length(x)/2)]
y <- gsub("(^ +)|( +$)","",x)
works
Now, both works!!!
So, I am puzzle!!! I cannot locate the problem.
Thank you for your advice.
Kenneth
