Plot normal, left and right skewed distribution in R

Question

I want to create 3 plots for illustration purposes: - normal distribution - right skewed distribution - left skewed distribution

This should be an easy task, but I fo

Answer 1

Finally I got it working, but with both of your help, but I was relying on this site.

 N <- 10000
 x <- rnbinom(N, 10, .5)
 hist(x, 
 xlim=c(min(x),max(x)), probability=T, nclass=max(x)-min(x)+1, 
   col='lightblue', xlab=' ', ylab=' ', axes=F,
   main='Positive Skewed')
lines(density(x,bw=1), col='red', lwd=3)

This is also a valid solution:

curve(dbeta(x,8,4),xlim=c(0,1))
title(main="posterior distrobution of p")
