[BioC] inSilicoMerging:::mergeCOMBAT covariates

[Quentin De Clerck]

Hi François,

I am sorry for the confusion. Indeed the package do not handle covariates, but we plan to integrate this in next release. In the meantime I suggest you to take a look at the BatchAdjust method in the latest SCAN.UPC package.

Kind regards,

Quentin De Clerck
