SparseArray-Logic-methods: 'Logic' operations on SparseArray objects

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

'Logic' operations on SparseArray objects

Description

SparseArray derivatives support operations from the Logic group, with some restrictions. See ?S4groupGeneric in the methods package for more information about the Logic group generic.

IMPORTANT NOTES:

• Only SVT_SparseArray objects are supported at the moment. Support for COO_SparseArray objects might be added in the future.

• In base R, Logic operations (i.e. & and |) support input of type() "logical", "integer", "double", or "complex". However, the corresponding methods for SVT_SparseArray objects only support objects of type() "logical" for now.

Value

A SparseArray derivative of the same dimensions as the input object(s).

Examples

svt1 <- svt2 <- SVT_SparseArray(dim=c(15, 6))
svt1[cbind(1:15, 2)] <- c(TRUE, FALSE, NA)
svt1[cbind(1:15, 5)] <- c(TRUE, NA, NA, FALSE, TRUE)
svt2[c(2, 6, 12:17, 22:33, 55, 59:62, 90)] <- c(TRUE, NA)

svt1 & svt2
svt1 | svt2

## Sanity checks:
m1 <- as.matrix(svt1)
m2 <- as.matrix(svt2)
stopifnot(
  identical(as.matrix(svt1 & svt2), m1 & m2),
  identical(as.matrix(svt1 | svt2), m1 | m2)
)
