[R] data - data matrix that can be used in regressions

2006-12-21 Thread Ulrich Kaiser
Dear R users,

 

I have spent most of this day figuring out how to read STATA data into R
(which eventually worked) and to run a simple OLS regression. It seems
that the manuals are written in the most general and abstract way which
does not really make it easy to understand what's going on.

 

I'd be glad if somebody could save my day by:

 

telling me how to define a matrix from the variables I read into R's
memory, supposing that the variable are lkiosk and lvisits.

 

Thank you very much!

 

Best regards,

 

Uli

Mymatrix - cbind(lkiosk,lvisits)

Do a class(Mymatrix) to check this.

You might find a simple tutorial like
http://www.math.ilstu.edu/dhkim/Rstuff/Rtutor.html to
be of help. I certainly have.

Do a google search for

   cran contributed documentation

and at the first hit you will find numerous introductions that may be
of use to you.

Also read the last line of every post to r-help.
