cbind: Combine RGList, MAList, EList or EListRaw Objects

In limma: Linear Models for Microarray Data

Description

Combine a set of RGList, MAList, EList or EListRaw objects.

Usage

## S3 method for class 'RGList'
cbind(..., deparse.level=1)
## S3 method for class 'RGList'
rbind(..., deparse.level=1)

Arguments

...	RGList, MAList, EList or EListRaw objects.
deparse.level	not currently used, see cbind in the base package

Details

cbind combines data objects assuming the same probes in the same order but different arrays. rbind combines data objects assuming equivalent arrays, i.e., the same RNA targets, but different probes.

For cbind, the matrices of expression data from the individual objects are cbinded. The data.frames of target information, if they exist, are rbinded. The combined data object will preserve any additional components or attributes found in the first object to be combined. For rbind, the matrices of expression data are rbinded while the target information, in any, is unchanged.

Value

An RGList, MAList, EList or EListRaw object holding data from all the arrays and all genes from the individual objects.

Examples

M <- A <- matrix(11:14,4,2)
rownames(M) <- rownames(A) <- c("a","b","c","d")
colnames(M) <- colnames(A) <- c("A1","A2")
MA1 <- new("MAList",list(M=M,A=A))

M <- A <- matrix(21:24,4,2)
rownames(M) <- rownames(A) <- c("a","b","c","d")
colnames(M) <- colnames(A) <- c("B1","B2")
MA2 <- new("MAList",list(M=M,A=A))

cbind(MA1,MA2)

Example output
