Hi,
I?m an R beginner and I'd really appreciate an hand?
I'd like to create a new column in a dataframe in wich will be print the
content of several other columns.
For instance :
I?ve got 2 columns : "site" ? "sampling number" and I would
like to create a
third column "ID", in wich will appear both the site name and the
sampling
number, like :
"site" "sampling" "ID"
site1 1 site1.1
site1 2 site1.2
site2 1 site2.1
site3 1 site3.1
How could I do that in R? If someone could help me it'd be great, thanks in
advance !
Zo?
