Or a possible alternative still using matplot: matplot(DF[, 3:4], type = "b", xaxt = "n", pch = c(21, 22), col = "black", lty = c("dotted", "solid"), ylab = "Y Vals", xlab = "Groups")
axis(1, at = 1:5, labels = as.character(DF$x.orig)) legend("topright", legend = c("Group 1", "Group 2"), lty = c("dotted", "solid"), pch = c(21, 22)) See ?points for different point symbols (pch) if you prefer.
