Hello, I am relatively new to R and am using it to run Classification and Regression Tree analysis. My only issue at this point is that numbers are always cut off on the lower nodes. I've tried changing the margins with mai=c(0, 0.5, 0.5, 0) but this has not so far worked. Any suggestions would be appreciated. Best, John Z. Metcalfe, M.D., M.P.H. Division of Pulmonary and Critical
