merge2ExpressionSets: Merge two ExpressionSet-objects into one ExpressionSet-object

Description

Merge two ExpressionSet-objects into one ExpressionSet-object

Usage

merge2ExpressionSets(GEdata1, GEdata2, verbose=TRUE)

Arguments

GEdata1

Object of class ExpressionSet.

GEdata2

Object of class ExpressionSet.

verbose

Logical indicator: should intermediate output be printed on the screen?

Value

Object of class ExpressionSet, restricted to the specified subset of features.

Details

Data of the two objects is assumed to originate from the same samples, and are presented in the same order.

Only the experimental data and annotation information is inherited by the merged object.

Examples

# load data
data(pollackGE16) 

# create two cghCall-objects
ids1 <- sample(1:dim(pollackGE16)[1], 10) 
GEdata1 <- pollackGE16[ids1,] 
GEdata2 <- pollackGE16[-ids1,] 

# order the copy number data genomically
pollackGE16 <- merge2ExpressionSets(GEdata1, GEdata2)
