Hi everyone. I have a DF with the first column being my independant variable and all other columns the dependent variables.
Something like: x y1 y2 y3 ... ... ... ... ... ... ... ... What I'm trying to do is to perform a linear model for each of my "y". It is pretty simple with loops, but I'm trying to vectorize it using *apply*. For instance, I tried something like: apply(DF, 1, function(DF){lm(DF[,1] ~ Band1[,2:5])}) But apparently it does not work. Any help would be greatly appreciated.
