combo: Combine MethyLumiSet objects

In wateRmelon: Illumina 450 methylation array normalization and metrics

Description

This is a wrapper for combining different MethyLumiSet objects.

Usage

combo(...)

Arguments

...	Eventually, any number of MethyLumiSet objects. Currently only guaranteed for 2 objects.

Details

This is a wrapper for methylumi::combine, which works around a name clash with a different combine function from the gdata package, and also a bug in methylumi::combine.

Value

a MethyLumiSet. The assayData, QCdata, experimentData, protocolData and phenoData are joined on sampleName . featureData and annotation are taken from the object given in the first argument

Note

the function uses sampleNames and gets rid of duplicates. Numeric sampleNames cause problems (and are a Bad Idea anyway). They should be turned into names with make.names() first.
