SparseArray-subassignment: SparseArray subassignment

In Bioconductor/SparseArray: High-performance sparse data representation and manipulation in R

SparseArray subassignment

Description

Like ordinary arrays in base R, SparseArray derivatives support subassignment via the [<- operator.

See Also

• [<- in base R.

• SparseArray objects.

• Ordinary array objects in base R.

Examples

a <- array(0L, dim=5:3)
a[c(1:2, 8, 10, 15:17, 20, 24, 40, 56:60)] <- (1:15)*10L
svt <- SparseArray(a)
svt

svt[5:3, c(4,2,4), 2:3] <- -99L

## Sanity checks:
a[5:3, c(4,2,4), 2:3] <- -99L
stopifnot(identical(as.array(svt), a), identical(svt, SparseArray(a)))
