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 !
