[R] multivariate analysis

[Kjetil Halvorsen]

if you want linear models (not specified), something like this should work:

Put your 1800 response variables (as columns) in a nx1800 matrix
resp_mat, and then
lm(resp_mat ~ latitude*age)   # interactions
lm(resp_mat ~ latitude+age   # without interactions
