[R-sig-eco] Using multiple species data for gam

[Rajendra Mohan panda]

Dear All

I have >1000 species with presence and absence (0 or 1) values and with
seven corresponding predictor variables. If I can run gam/glm for the data
using all species data simultaneously vs predictors. Data are arranged in
columns against their GPS locations (see below). I know it is possible to
do separately for each species.

Your kind response is highly appreciated.
