vl_lmcR: Run the CCG 'vl_lmc' to Automatically Model Multivariate...

In truemoid/rgslib: R Interface to GSLIB/CCG Programs

Description

vl_lmcR is an interface to the Fortran program varfit_lmc. It auotmaticaly models direct and cross variograms given experimental points and models fo the direct variograms.

Usage

vl_lmcR(nvars, corr0, corr, varcalcs = "vg_", varfits = "vm_",
  invdistwt = TRUE, npairswt = TRUE, minpairs = 10, maxiter = 100,
  varfitslmc = "vl_", corrs = "corrs.txt")

Arguments

nvars	Scalar numeric: number of variables being modelled.
corr0	Numeric vector: cross-variogram nugget effects.
corr	Numeric matrix: correlation matrix (e.g., from cor).
varcalcs	Character: prefix of experimental variogram files.
varfits	Character: prefix of direct variogram model files.
invdistwt	Boolean: inverse distance weighting.
npairswt	Boolean: number of pairs weighting.
minpairs	Scalar integer: minimum pairs.
maxiter	Scalar integer: number of fitting iterations.
varfitslmc	Character: prefix of output variogram model files.
corrs	Character: output correlation matrix system file.

Value

A list with two data frames: model contains the variogram models and corrs contains the model cross-variogram sills for validation.
