Dear All, I have a data as follows: ID <- 1:100 Y <- rnorm(100) X <- rnorm(100) type <- as.factor(rep(1:3,100,time=1)) df <- as.data.frame(cbind(ID, Y,X,type)) I want to plot Y versus X by specifying the pch to be as follows: Subjects having type = 1 must be plotted with a character pch = "A" Subjects having type = 2 must be plotted

I have a series of data frames that are identical structurally, i.e. - made with the same code, but I need to add them together so that they become one, longer, data frame, i.e. - each of the slot vectors are increased in length by the length of the added data frame vectors. So if I have df1 with a slot A so that length(df1$A) = 100 and I have df2 with a slot A so that length(df2$A)=200 then I
