But that's vastly under specified; there's no such thing as _the_ skewed distribution. You simply need to pick a skewed distribution and then plot it however you want. You've already been pointed to one resource on how to do so.

How about something like this? 

layout(1:3)
x <- rnorm(1e5, 4, 1)
plot(density(x))
plot(density(log(x)))
plot(density(exp(x)))
