Dears R
I am a self taught novice user of R. I begin to understand its
philosophy and some basics like objects, vectors, arrays, lists
etc...I still am not able to manipulate variables (objects!) in
dataframes (objects also !!!) already imported from my usual
statistical package (stata 10/SE) despite carefull lecture of some
good books (R Introduction, R Book of Crowley etc...). How must I
proceed in order to go over this ostacle?
If I understand correctly, you have trouble importing Stata files.
Have you tried library(Rcmdr), Data > Import > Stata ? I think that
JGR and Rattle also provide some graphical facilities for this.
That wasn't what I understood him to be asking, but rather how to
create new variables within existing dataframes. My suggestion would
be to work with the examples on the help(with) and help(transform)
pages.
