Value

a R object or a memory-mapped object (depending on houba("max.size"))

Arguments

x

memory-mapped object

i, j

indices of elements to extract or replace

...

supplementary indices (for arrays)

value

replacement value

drop

for dual matrices or array.

Examples

a <- matrix(1:6, 2, 3)
A <- as.mmatrix(a)
A[1,]
A[2,] <- A[1,] * 2
A[,3] <- 6:7
A
