Extending data frame with longer columns
Hi,
I am a beginner in R and have only read a few chapters in the R book,
I was not able to find a solution for this simple problem.
I have an empty data frame:
a=data.frame(name="test")
which I would like to extend in a for-loop (with data extracted from a
database). Ideally I would like to extend the data frame like this:
a["new_1"] = 1:10
a["new_1"] = 1:12
