Re: [R] Add columns of dataset

Lisa - I think something like this will do what you want: mydf = data.frame(id=1:3,var1=c(0,.4,0),var2=c(.1,.6,0),var4=c(.3,0,0),var7=c(.9,0,.8),var8=c(0,.2,.7)) allvars = c('id',paste('var',1:8,sep='')) mydf[,allvars[!allvars %in% names(mydf)]] = 0 mydf = mydf[,sort(names(mydf))] mydf id
