merge2cghCalls: Merge two cghCall-objects into one cghCall-object

Description

Merge two cghCall-objects into one cghCall-object.

Usage

merge2cghCalls(CNdata1, CNdata2, verbose=TRUE)

Arguments

CNdata1

Object of class cghCall.

CNdata2

Object of class cghCall.

verbose

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

Value

Object of class cghCall, 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(pollackCN16) 

# create two cghCall-objects
ids1 <- sample(1:dim(pollackCN16)[1], 10) 
CNdata1 <- pollackCN16[ids1,] 
CNdata2 <- pollackCN16[-ids1,]
