Update Subset

Updates elements of an array at specified positions, returning a new array. You can also use the [<- operator.

Usage

nv_subset_assign(x, ..., value)

Arguments

x

(arrayish)
The array to update. Can be any data type. An R object is materialized at its default data type.

...

Subset specifications, one per axis. See vignette("subsetting") for details.

value

(arrayish)
Replacement values. Scalars are broadcast to the subset shape and non-scalar values must match it. The value is converted to the data type of x.

Value

(arrayish)
Has x's data type and shape, with the subset replaced.

Examples

x <- nv_matrix(1:12, nrow = 3)
# set row 1 to zeros
nv_subset_assign(x, 1, value = nv_scalar(0L))
#> AnvlArray
#>   0  0  0  0
#>   2  5  8 11
#>   3  6  9 12
#> [ CPUi32{3,4} ] 
x[1, ] <- nv_scalar(0L)
x
#> AnvlArray
#>   0  0  0  0
#>   2  5  8 11
#>   3  6  9 12
#> [ CPUi32{3,4} ]
