ConvertSupport

R Documentation

Convert support of a mu/phi/cov etc. to and from obsGrid and workGrid

Description

Convert the support of a given function 1-D or 2-D function from fromGrid to toGrid. Both grids need to be sorted. This is an interpolation/convenience function.

Usage

ConvertSupport(
  fromGrid,
  toGrid,
  mu = NULL,
  Cov = NULL,
  phi = NULL,
  isCrossCov = FALSE
)

Arguments

`fromGrid`	vector of points with input grid to interpolate from
`toGrid`	vector of points with the target grid to interpolate on
`mu`	any vector of function to be interpolated
`Cov`	a square matrix supported on fromGrid * fromGrid, to be interpolated to toGrid * toGrid.
`phi`	any matrix, each column containing a function to be interpolated
`isCrossCov`	logical, indicating whether the input covariance is a cross-covariance. If so then the output is not made symmetric.
