Hello,

I am trying to translate a matlab program into R, and I have some problems to find out how to translate the PPVAL function. I know that ppval(pp,xx) returns the value at the points xx of the piecewise polynomial contained in pp( constructed by spline), but I don't know how to do the same thing in R.

Thanks for you help

Delphine
