Hi all, I fitted a model say with five xc<-lm( y~x1,x2,x3,x4,x5) I want to plot the residuals for each factor and I used this, plot(xc,residuals=TRUE,se=TRUE,pch=".") I only get the plot of the last factor (i.e., x5). I think it is overwriting. How can I send the five plots into a file? I usually use cut and paste and this may not be the right thing to do. Thanks in

Dear all I am trying to learn R I was trying to calculate standard deviation here are the commands and outputs in R > sd(Ht_cm[type=='SD'])[1] 3.283605> sd(Ht_cm[from_treeline=='above'])[1] 16.83289> sd(Ht_cm[type=='SD'][from_treeline=='above'])[1] NA> the problem is that, i could not understand why the third command could not give any result.
