Function designed to find the phi parameter such that the
correlation between points within a given distance d is at most a
given value.

)a numeric value indicating the range parameter such that the
spatial correlation between two points at distance d is
cut.
maximum distance for spatial dependence equal to cut.
smoothness parameter associated with the Matern cov. function.
one of the smoothness parameters associated with the Generalized Wendland covariance function
one of the smoothness parameters associated with the Generalized Wendland covariance function
covariance function family, the options are c("matern",
"gw", "cs", "spher", "pexp", "gaussian").
Minimum and maximum distance to be considered. The default is
range = c(1e-04, 1000).
desired spatial correlation at a distance d, the default is
cut = .05.
