I would like to filter - or subset - the dataset for $Sex = 1 (in this
case means male...), for example...
thanks anyway,

It is.
For example, if you have a variable stored as a vector named "x",
and another variable stored as aa vector named "y", you can select
cases of y where x is greater than 3 by using
y[x>3]
However, you're going to have to provide more information in order
to get a better answer than that (see the posting guide, link
included with every post to r-help). In particular, I'm guessing
that the answer you really want looks somewhat different than my
example -- but this depends on the exact structure of what
read.spss() produces.
I'd also suggest reading some of the documentation available from
the R website (CRAN), notably, "An Introduction to R".

dear list,
I have read a spss file with read.spss()
now I have a list with all my variable stored as vectors.
is it possible to selec cases based on the value of one or more
variables?
thank you,
Simone
