Subject: [R] cubic spline curves

I have a question about how to generate monthly data from quarterly data:

What I want to do is basically fits cubic spline curves to the quarterly data to form continuous-time approximations of the input series, and then generate output series (monthly data) from the spline approximations.

SAS can do it using proc expand:

Anyone know how to do it in R? Any input is appreciated.
