[R] problem about R

[Rui Barradas]

Hello,

What is a dataset? In R there are lots of types, including 'data.frame' 
and 'list'. And R's type 'factor' corresponds to categorical variables. 
You must be more specific, show us an example dataset using dput().

dput( head(x, 30) )  # paste the output of this in a post


Hope this helps,

Rui Barradas
