Hello, thank you very much for your answer. I have now found a way to increase the RAM scale factor. It actually works when I write the RAM scale factor inside the function like this : fit(plm,ram=50,verbose=verbose) But it does not work If I write the RAM scale factor like this : setOption(aromaSettings,"memory/ram",50.0) fit(plm,verbose=verbose) In that case it always takes 1 as RAM scale factor. Sincerly yours Jean-Paul
