Combine RGList or MAList Objects


Combine a series of RGList objects or combine a series of MAList objects.

... RGList objects or MAList objects
deparse.level not currently used, see cbind in the base package


cbind combines data objects assuming the same gene lists but different arrays. rbind combines data objects assuming equivalent arrays, i.e., the same RNA targets, but different genes.

For cbind, the matrices of expression data from the individual objects are cbinded. The data.frames of target information, if they exist, are rbinded. The combined data object will preserve any additional components or attributes found in the first object to be combined. For rbind, the matrices of expression data are rbinded while the target information, in any, is unchanged.


An RGList or MAList object holding data from all the arrays and all genes from the individual objects.
