Description
Interpolates tabulated values via Lagrange interpolation
Usage
1
LagrangeInterpolate(.x, .n, .D)
Arguments
.x
Value of variable #1 for which interpolated result is to be returned
.n
Number of points to use (order of polynomial will be .n-1).
The value provided must be in the range from 2 to 10; otherwise NA is returned.
.D
Data.frame containing the two variables to use for interpolation
Details
The routine takes as input a data.frame with two variables, one
to be used for interpolation of values in the second. It returns the
value of the second variable corresponding to the provided value
of the first variable.
Value
The interpolated value of variable #2 corresponding to the
value provided for variable #1 (.x)
