subset: Subset an MVST object

In shazhe/mvst0: Multi-variate ST modelling on globe

Description

This function can be used to subset observations, meshes, and latent fields in the usual manner of subset.

Usage

subset(x, ...)

## S4 method for signature 'Basis'
subset(x, ...)

## S4 method for signature 'GMRF_basis'
subset(x, ...)

## S4 method for signature 'GMRF'
subset(x, ...)

## S4 method for signature 'Obs'
subset(x, ...)

## S4 method for signature 'Obs_poly'
subset(x, ...)

Arguments

x	the MVST object
...	relations pertaining to the data frame within the MVST object

Value

object of the same class as x unless x is a mesh, in which case a data frame is returned.

Examples

data(icesat)
icesat_obs <- Obs(df=icesat)
icesat_sub <- subset(icesat_obs,t==3)
print(class(icesat_sub))

data(surf_fe)
Mesh <- initFEbasis(p=surf_fe$p, t = surf_fe$t, M = surf_fe$M, K = surf_fe$K)
Mesh_sub <- subset(Mesh,x < 0)
print(class(Mesh_sub))
