merge2cghCalls {sigaR} | R Documentation |
Merge two cghCall-objects into one cghCall-object.
merge2cghCalls(CNdata1, CNdata2, verbose=TRUE)
CNdata1 |
Object of class |
CNdata2 |
Object of class |
verbose |
Logical indicator: should intermediate output be printed on the screen? |
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.
