Hei,
I am trying to fit an ANOVA-model by lm. I get the error-message
Error in lm.fit(x, y, offset = offset, ...) :
negative length vectors are not allowed
which I don't understand. My data looks fine, but one factor has
extremely many levels. Does anyone have a tip?
Not really. It sounds like it might be a bug. How many levels? Can you generate a simple example (possibly with simulated data) showing the same behaviour?
