Interpolate Values of Array

For each row in matrix x, the hypercube of a containing this point is searched. The corners of the hypercube are linearly interpolated. By default, dimnames(a) is taken to contain the coordinate values for each point in a. This can be overridden using adims. If method=="constant", the value of the ``lower left'' corner of the hypercube is returned.

Keywords
multivariate, arith
Usage
interpolate(x, a, adims=lapply(dimnames(a), as.numeric),
            method="linear")
Arguments
x

Matrix of values at which interpolation shall take place.

a

Array of arbitrary dimension.

adims

List of the same structure as dimnames(a).

method

Interpolation method, one of "linear" or "constant".
