Row and column summary methods for adgeMatrix

Compute row or column sums and means for an adgeMatrix, dispatching through the amatrix backend when GPU acceleration is available.

Usage

# S4 method for class 'adgeMatrix'
rowSums(x, na.rm = FALSE, dims = 1L)

# S4 method for class 'adgeMatrix'
colSums(x, na.rm = FALSE, dims = 1L)

# S4 method for class 'adgeMatrix'
rowMeans(x, na.rm = FALSE, dims = 1L)

# S4 method for class 'adgeMatrix'
colMeans(x, na.rm = FALSE, dims = 1L)

Arguments

x

An adgeMatrix.

na.rm

Logical; if TRUE, NA values are ignored.

dims

Integer; dimensions to sum over (passed to the backend).

Value

A numeric vector of length equal to the number of rows or columns.

Examples

A <- adgeMatrix(matrix(1:12, 3, 4))
rowSums(A)
#> [1] 22 26 30
colMeans(A)
#> [1]  2  5  8 11
