RFC: spline / splinefun (etc) amalgamation
Tue, 26 May 1998 10:25:24 +1200 (NZST)
At present R has separate functions "spline" and "splinefun". The first
of these carries out spline interpolation of a data set and returns the
interpolated values; the second returns the interpolating function itself
(approx and approxfun are similar).
I would like to combine these into a single function "spline" with
an (optional) argument which determines which kind of value is returned.
spline(x,y) # return interpolated function
spline(x,y,fun=T) # return the interpolating function
I would also like to propose this as a standard for smoothing and
interpolating functions. This has a couple of advantages - fewer
names to remember and, the ability to use the function form in
model fitting code ("predict" for example).
Any objections or comments?
