[R] Files with Missing Data

[Setlhare Lekgatlhamang]

Hi Norman,

If you still have not managed, google for "Econometrics in R" pdf paper
by Farnsworth; it as helped me a lot. You will only need to replace
Farnsworth's read function with the read.csv function suggested below by
Erik.

You can use Peter's advice; also note there is a read.csv function.  A
thorough 
reading of the ?read.table help page is very useful I've found.

There is also an R data import/export manual on CRAN.
