rbind(df1, df2)
This is a very basic question. You probably would
save a lot of time if you read some of the
documentation on the CRAN site (not the home R page).
Click on "Contributed" on the left side of the screen
and have a look at some of the documentation there.
There are some excellent materials there.
I'd recommend perhaps looking at Simple R by John
Verzani and A Guide for the Unwilling S User by
Patrick Burns. R and S are basically equivalent for
this purpose.
Good luck and don't forget to read the posting guide.
