[R] Plot Mixtures of Synthetically Generated Gamma Distributions

[Gundala Viswanath]

Hi,

I have the following vector
which is created from 3 distinct distribution (three components) of gamma:

x=c(rgamma(30,shape=.2,scale=14),rgamma(30,shape=12,scale=10),rgamma(30,shape=5,scale=6))

I want to plot the density curve of X, in a way that it shows
a distinct 3 curves that represent each component.

How can I do that?

I tried this but doesn't work:

lines(density(x))

Please advise.
