intpol.irregular: Interpolation on an irregular grid

In baccione-eawag/EawagSchoolTools: Miscellaneous Tools for Eawag Summer School in Environmental Systems Analysis

Description

Function to perform interpolation on an irregular grid.

Usage

intpol.irregular(x,x.data,y.data,method=c("neighbor","invdist"),
                 scales.x=NA,fact=1)

Arguments

x	vector of values of independent variable at which to interpolate; xout can also be a matrix, interpolation is then for each row
x.data	matrix of independent independent variables; each row of x.data belongs to one input specification (x.data can be a vector if there is only one input dimension)
y.data	vector of values of the dependent variable; one value for each row of x.data
method	"neighbor" does nearest neighbor interpolation (piecewise constant function of value at nearest data point); "invdist" weights the provided dependent values according to the inverse of the distance to xout squared
scales.x	values of x and of x.data are scaled by these scales before interpolation; default is all scales equal to 1
fact	scaling factor

Value

Returns interpolated values.
