Dear Gundala,
It's just a starting points and I'm sure completely sure it will be
improved. Try this (for now):
set.seed(123)
x=c(
rgamma(30,shape=.2,scale=14),
rgamma(30,shape=12,scale=10),
rgamma(30,shape=5,scale=6))
plot(density(x[1:30]),col=2,xlim=range(0,max(density(x)$x)),type='l',main="Density
for your vector")
points(density(x[31:60]),col=1,type='l')
points(density(x[61:90]),col=4,type='l')
legend("topright",paste('Type',1:3,sep=""),col=c(2,1,4),lty=1)
Also, see ?density, ?points and ?plot for more information.
HTH,
Jorge
