\description{
Several constants are provided that might make
the use of some functions easier, e.g. \command{\link{RFgetModelNames}}
}
\value{
\code{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")}
\code{RC_DOMAIN_NAMES = c("single variable", "kernel", "framework dependent", "mismatch")
}
\code{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>")
}
\code{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")
}
\code{RC_ISOTROPIC} gives the numerical code for option
\code{"isotropic"}
\code{RC_SPACEISOTROPIC} gives the numerical code for option
\code{"space-isotropic"}
\code{RC_CARTESIAN_COORD} gives the numerical code for option
\code{"cartesian system"}
\code{RC_GNOMONIC_PROJ} gives the numerical code for
the gnomonic projection, see also \code{zenit} in \code{\link{RFoptions}}.
\code{RC_ORTHOGRAPHIC_PROJ} gives the numerical code for
the orthographic
projection, see also \code{zenit} in \code{\link{RFoptions}}.
\code{RC_EARTH_COORDS} gives the numerical code for option
\code{"earth coordinates"}
\code{RC_SPHERICAL_COORDS} gives the numerical code for option
\code{"earth coordinates"}
\code{RC_OPTIMISER_NAMES} and \code{RC_NLOPTR_NAMES} give the
names for the options \code{optimiser} and \code{algorithm},
respectively, \code{RFfitoptimiser}.
\code{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.
