abind: Combine multidimensional array-like objects

In Bioconductor/S4Arrays: Foundation of array-like containers in Bioconductor

Combine multidimensional array-like objects

Description

Bind multidimensional array-like objects along any dimension.

NOTE: This man page is for the abind S4 generic function defined in the S4Arrays package. See ?abind::abind for the default method (defined in the abind package). Bioconductor packages can define specific methods for objects not supported by the default method.

Usage

## Bind array-like objects along any dimension:
abind(..., along=NULL, rev.along=NULL)

## Bind array-like objects along their first or second dimension:
arbind(...)
acbind(...)

Arguments

...	The array-like objects to bind.
along, rev.along	See ?abind::abind for a description of these arguments.

Value

An array-like object, typically of the same class as the input objects if they all have the same class.

See Also

• abind::abind in the abind package for the default abind method.

• rbind and cbind in the base package for the corresponding operations on matrix-like objects.

Examples

a1 <- array(1:60, c(3, 5, 4),
            dimnames=list(NULL, paste0("A1y", 1:5), NULL))
a2 <- array(101:240, c(7, 5, 4),
            dimnames=list(paste0("A2x", 1:7), paste0("A2y", 1:5), NULL))
a3 <- array(10001:10100, c(5, 5, 4),
            dimnames=list(paste0("A3x", 1:5), NULL, paste0("A3z", 1:4)))

abind(a1, a2, a3, along=1)  # same as 'arbind(a1, a2, a3)'

m2 <- matrix(1:35, nrow=7)
abind(m2, a2, along=3)
abind(a2, m2, along=3)

abind(m2, m2+0.5, rev.along=0)  # same as 'abind(m2, m2+0.5, along=3)'
