R: Constants used in RandomFields (RC constants)

Constants {RandomFields} | R Documentation

## Constants used in RandomFields (RC constants)

### Description

Several constants are provided that might make the use of some functions easier, e.g. `RFgetModelNames`

### Value

`RC_TYPENAMES = c("tail correlation function", "positive definite", "variogram", "negative definite", "process", "method for Gauss process", "method for Brown-Resnick process", "shifted shape function", "distribution family", "shape function", "trend", "interface", "undefined", "other type")`

`RC_DOMAIN_NAMES = c("single variable", "kernel", "framework dependent", "mismatch")`

`RC_ISONAMES = c("isotropic", "space-isotropic", "zero-space-isotropic", "vector-isotropic", "symmetric", "cartesian system", "earth system", "spherical system", "cylinder system", "non-dimension-reducing", "parameter dependent", "<mismatch>")`

`RC_MONOTONE_NAMES = c("mismatch in monotonicity", "submodel dependent monotonicity", "previous model dependent monotonicity", "parameter dependent monotonicity", "not monotone", "monotone", "Gneiting-Schaback class", "normal mixture", "completely monotone", "Bernstein")`

`RC_ISOTROPIC` gives the numerical code for option `"isotropic"`

`RC_SPACEISOTROPIC` gives the numerical code for option `"space-isotropic"`

`RC_CARTESIAN_COORD` gives the numerical code for option `"cartesian system"`

`RC_GNOMONIC_PROJ` gives the numerical code for the gnomonic projection, see also `zenit` in `RFoptions`.

`RC_ORTHOGRAPHIC_PROJ` gives the numerical code for the orthographic projection, see also `zenit` in `RFoptions`.

`RC_EARTH_COORDS` gives the numerical code for option `"earth coordinates"`

`RC_SPHERICAL_COORDS` gives the numerical code for option `"earth coordinates"`

`RC_OPTIMISER_NAMES` and `RC_NLOPTR_NAMES` give the names for the options `optimiser` and `algorithm`, respectively, `RFfitoptimiser`.

`RC_LIKELIHOOD_NAMES = c("auto", "full", "composite", "tesselation")` gives the names of the ML variants: (i) internal choice according to the number of data, (ii) full likelihood, (iii) (pairwise) composite likelihood, and (iv) composite likelihood based on a tesselation of the space.

### Examples

    RFoptions(seed=0) ## *ANY* simulation will have the random seed 0; set
    ##                   RFoptions(seed=NA) to make them all random again

    RC_ISONAMES
    RC_ISONAMES[RC_ISOTROPIC:RC_CARTESIAN_COORD + 1]
    RFgetModelNames(isotropy=RC_ISONAMES[RC_ISOTROPIC:RC_CARTESIAN_COORD + 1])
