R help - Jul 2006 - DIfferent lengths

Dear List members,

       I am having a problem importing SPSS files. For some reason I do not
understand, the variables in the data set come into R with different
lengths, which seems to make regression analysis impossible.

       The strangest thing is this: it SOMETIMES work. I ran the same
commands (always pasting the same thing from RWinEdt) yesterday, and,
although it took a long time for R to do it (and thought it sometimes
crashed in the process), it worked. Still, today, the same commands (pasted
from the same RWinEdt file, using the very same SPSS files) produced this
error message about different lengths.

        Does anyone know what the problem could be?

        Thanks in advance,

                                          Celso Barros
