Greetings helpRs --
I would like to use plot() to plot two cumulative distribution curves so
that a user of the plot can compare the distributions of the two
variables. The following code draws two distributions separately, but I
cannot find the instruction necessary to add a second cumulative
distribution to the first one.
Any suggestion would be very welcome.
x1 <- sort(rnorm(1000,50,10))
x2 <- sort(rnorm(1000,40,8))
plot(x1,1:length(x1)/length(x1),type="l")
plot(x2,1:length(x2)/length(x2),type="l")
grid(col = "black")
