Plot two graphs in a same plot
ggplot2, plot, r, r-faq
Solution
`lines()` or `points()` will add to the existing graph, but will not create a new window. So you'd need to do
plot(x,y1,type="l",col="red")
lines(x,y2,col="green")
Problem
I would like to plot y1 and y2 in the same plot. ``` x <- seq(-2, 2, 0.05) y1 <- pnorm(x) y2 <- pnorm(x, 1, 1) plot(x, y1, type = "l", col = "red") plot(x, y2, type = "l", col = "green") ``` But when I do it like this, they are not plotted in the same plot together. In Matlab one can do `hold on`, but does anyone know how to do this in R?
