R help - Jan 2005 - Query: simple autocorrelation ina time series

I hope you can help with what might be an easy query.

I am doing some simple simulations where I am generating series of data
from a normal distribution using rnorm. I am then treating these as a
time series. I want to know how I can incorporate correlation in the
series (autocorrelation) i.e. make the observations non-independent,
with a known (but simple) correlation structure. In other words I want
to simulate correlated data.

Many thanks for your help.

You need mvrnorm() to do this.
