Hi list, I tried to convert a data.frame into a matrix using data.matrix. Unfortunately my matrix contains missing values (NA) wherefore all columns including NA's were changed into factors.
I thought that many people stumbled across that problem already wherefore there must be a simple solution. But it seems there isn't. I tried lapply, replace and other things in combination but still did not manage to convert my data.frame into a proper matrix with numeric values. Any advice?
