Thank you Jeff for your response.
My y1, y2, y3 are actually 3 columns in the data so I cannot use the c()
function to concatenate them. I am confusing the "columns" with
vectors. I actually meant columns.
Any help will be much appreciated

I am sure you can use c() because columns may be vectors even though vectors are
not columns, but you really need to follow the posting guide and provide a
reproducible example for us to show you how. You might find [1] helpful, in
particular as it describes the use of the dput function to give us a few rows of
your data.

Hi Olufemi, I sounds like you have a data frame (let's call it "mydata") with at least three elements (columns). You may be trying to use c() in this way: y1to3<-c(y1,y2,y3) in which case it won't work. However: y1to3<-c(mydata$y1,mydata$y2,mydata$y3) might do what you want, substituting whatever the name of your data frame is for "mydata".
