I have obtained from a paper next results:
Variable 1: Mean=165, sd=15
Variable 2: Mean=149, sd=18
Variable 3: Mean=134, sd=25
I have simulated normal distributions using rnorm. This is the way (with a n=1000): rnorm(1000,165,15). The same procedure with the others.
So now I want a common graph that shows the 3 normal distributions (density plots) at the same time. And also, that each of the density plots shows standard deviations bounds (1 and 2 sigmas) and if possible, means. This may be represented as vertical lines from the X axis til the curve of the plot.
Anybody knows which is the exact code in R?
