Just a couple of notes. * What you are attempting to fit here is a linear model, or, more precisely 13112 simple linear regressions. Why not just use 'lm'? 'glm' is for fitting generalized linear models and using it for this special case is going to be computationally costly. [NB the concept of a 'general' linear model is foreign to R.]
* If ever you do manage to fit you 13112 simple linear regressions, what then? * Since thery really are separate models, why not try doing it in smaller batches, the first 1000, the next 1000, and so on?

The first column corresponds to the predictor (data.spect[,1]) and the rest to the response variables (data.spect[,2:13113]). When I try this code glmObject <- glm(data.spect[,2:13113]~data.spect[,1]) I get the following error: Error: (subscript) logical subscript too long Could anyone help me on solving this problem?
