nres: Return the number of resolutions

Description

Return the number of resolutions from a basis function object.

Usage

nres(b)
# S4 method for Basis
nres(b)
# S4 method for TensorP_Basis
nres(b)
# S4 method for SRE
nres(b)

Arguments

b

object of class Basis or SRE

See Also

auto_basis for automatically constructing basis functions and show_basis for visualising basis functions.

Examples

library(sp)
set.seed(1)
d <- data.frame(lon = runif(n=500,min = -179, max = 179),
                lat = runif(n=500,min = -90, max = 90),
                z = rnorm(500))
coordinates(d) <- ~lon + lat
slot(d, "proj4string") = CRS("+proj=longlat")

### Now create basis functions on sphere
G <- auto_basis(manifold = sphere(),data=d,
                nres = 2,prune=15,
                type = "bisquare",
                subsamp = 20000)
nres(G)
