getting a new factor
...1 Sphagnum subsecundum M A En 100
2 Sphagnum denticulatum M A En 200
3 Molinia caerulea M A En 300
4 Sphagnum flexuosum M A En 400
5 Juncus squarrosus M A En 500
6 Carex echinata M A En 600
I do need a new one with a new factor constructed from a concatenation of the two first columns, genus and species. I am guessing this must be a simple matter while working with R, but I am stuck at this point.
Any help will be welcome! Thanks.
