[R] graphing the normal distribution

Hello,

I'd like to make some simple example graphs of the normal distribution,
varying standard deviation, mean, and kurtosis across examples.

I have been able to manipulate mean and sd using rnorm and hist:
y_hist(rnorm(1000000, mean=100, sd=50), 50, plot=F)
plot(y$mid,y$count,type="l")

Two questions:

1) n=100000 seems like a lot of samples to approach a smooth
curve. Is there a way to make the curve smooth, but computationally less
demanding?

2) What can I do to change the "peakiness" of the distribution?

Many thanks in advance.

David
