# Overlay multiple types on the same plot plot(days, temp, type ="n", # First set up coordinate system without drawing main ="Monthly Temperature Change", xlab ="Date", ylab ="Temperature(°C)", ylim =c(0, 30)) # Add vertical lines (type = "h") lines(days, temp, type ="h", col="lightblue", lwd =2) # Add points and lines lines(days, temp, type ="o", col="coral", lwd =2, pch =19, cex =0.6) Executing the above code will display a temperature change chart with vertical lines and connecting lines overlaid.
