Thanks for your reply.
I know the exact values. The purpose is to find out the distribution function
if it is exponential, linear, etc.
Best,
Carol

Hi,
At the sampling points, do you know the function value "exactly" or
you only observe it with "noise"?
If it is the former, you can use an interpolation scheme, such as, for example,
interpSpline() in "splines" package.
If it is the latter, you can use a smoother, such as, for example,
smooth.spline() or loess().
Ravi.
