Bind DelayedArray objects along their rows or columns

Description

Methods for binding DelayedArray objects along their rows or columns.

Details

rbind, cbind, arbind, acbind methods are defined for DelayedArray objects. They perform delayed binding along the rows (rbind and arbind) or columns (cbind and acbind) of the objects passed to them.

See Also

• cbind in the base package for rbind/cbind'ing ordinary arrays.

• acbind in the IRanges package for arbind/acbind'ing ordinary arrays.

• DelayedArray-utils for common operations on DelayedArray objects.

• DelayedArray objects.

• HDF5Array objects in the HDF5Array package.

• array objects in base R.

Examples

## ---------------------------------------------------------------------
## rbind/cbind
## ---------------------------------------------------------------------
library(HDF5Array)
toy_h5 <- system.file("extdata", "toy.h5", package="HDF5Array")
h5ls(toy_h5)

M1 <- HDF5Array(toy_h5, "M1")
M2 <- HDF5Array(toy_h5, "M2")

M <- rbind(M1, t(M2))
M
colMeans(M)

## arbind/acbind
## ---------------------------------------------------------------------
a1 <- array(1:60, c(3, 5, 4),
            dimnames=list(NULL, paste0("M1y", 1:5), NULL))
a2 <- array(101:240, c(7, 5, 4),
            dimnames=list(paste0("M2x", 1:7), paste0("M2y", 1:5), NULL))
a3 <- array(10001:10100, c(5, 5, 4),
            dimnames=list(paste0("M3x", 1:5), NULL, paste0("M3z", 1:4)))

A1 <- DelayedArray(a1)
A2 <- DelayedArray(a2)
A3 <- DelayedArray(a3)
A <- arbind(A1, A2, A3)
A

## Sanity check:
stopifnot(identical(arbind(a1, a2, a3), as.array(A)))
