[R] interpolation

[Marwan Khawaja]

Hello,
I have 15 data points (weight at birth) by age which I want to interpolate back
in time (to 5 more age points).
There are many functions in R to do this and I wonder if anyone has experience
in using these -- any preference/caveat etc? I am trying to find an alternative
to linear interpolation.
Using R 1.6.0 under windows
TIA Marwan
