overlay plot question
Greetings all, I have two logistic plots coming from two calls to plogis. The code is .x <- seq(-7.6, 7.6, length=100) plot(.x, plogis(.x, location=0, scale=1), xlab="x", ylab="Density", main="Logistic Distribution: location = 0, scale = 1", type="l") abline(h=0, col="gray") .y <- seq(-7.6, 7.6, length=100) plot(.x, plogis(.x, location=2, scale=4), xlab="x", ylab="Density", main="Logistic Distribution: location = 2, scale = 4", type="l") abline(h=0, col="gray") remove(.x) remove(.y) I would like to overlay these on one plot. Notice here the y-axis is different. But I would like to axis to be 0 to 1 as in the first plot. Any suggestions would be greatly appreciated. Thanks in advance, David
