subset-.sk: Single-bracket assign

In snapKrig: Fast Kriging and Geostatistics on Grids with Kronecker Covariance

Single-bracket assign

Description

Behavior depends on the class of i. For character vectors, this assigns to the named list entries of x (as usual). For numeric indices, it assigns vectorized grid data values. For multi-layer objects, specify the layer in j and supply a matrix for replacement

Usage

## S3 replacement method for class 'sk'
x[i = NULL, j = NULL] <- value

Arguments

x	an sk object
i	column-vectorized index
j	index of layer (only for multi-layer x)
value	the replacement values

Value

the "sk" object with the specified subset replaced by value

Examples

g = sk_validate(list(gval=stats::rnorm(4^2), gdim=4, gres=0.5))
print(g)
g[1] = NA
print(g)
