As you got the error message, to use ggplot function, you had better make a data.frame with your data "d". for example, d[ n x p], n : observations, p : variables n = dim(d) dd = data.frame(x=d[,2:n[2]], y=d[,1]) then, you may get the better result after apply "dd" to the ggplot function.
> p1 + geom_line(aes(x=x,y=predict(m2,list(xv=x))), color="red") Error in data.frame(evaled, PANEL = data$PANEL) : arguments imply differing number of rows: 100, 18 This example is from "The R Book" by Michael J.
