I have a question about how to filter the data frame:
Suppose my data frame has variables like gender, age,... How to get a subset
of the data frame, with only female (or male) and/or age > 50...? What is
the typical syntax? I tried several condition expressions, but none of them
worked...
Thanks a lot!
I guess the other people answered the question already.
But may I ask if your background is in SPSS?
I just had this impression talking about 'filter' and the unique way of
using 'syntax'.
Best,
Roland
P.S. The first statistical software I used was SPSS and I would have
asked in exactly the same way when I started using R. :-)
