Hi
I have two basic questions, and here they go, but I was wondering as 
well where can I ask these basic questions without bothering  you 
people


I've used Splus and now I'm using R and there's some functions that I 
can't simply find

one:
sort.col
that allows data.frames to be sort by a given col
(I saw the funtion sort but that's for vectors. and I can't believe I 
can't find the function for data.frames)

the other function I wanted to know:
convert.col.type
that converts a given column of a data frame from let's say integer 
to characters

Once again I'm sorry for these basic questions and since predictably 
I'll have more of those if there's a basic-questions-list I would 
love to know more about it

thanks
