## Function to join CDF allele A and allele B groups strand by strand

### Description

Function to join CDF allele A and allele B groups strand by strand.

This `function` is design to be used with `applyCdfGroups`() on an Affymetrix Mapping (SNP) CDF `list` structure.

### Usage

    cdfMergeAlleles(groups, compReverseBases=FALSE, collapse="", ...)

### Arguments

`groups` | A `list` structure with groups.
`compReverseBases` | If `TRUE`, the group names, which typically are names for bases, are turned into their complementary bases for the reverse strand.
`collapse` | The `character` string used to collapse the allele A and the allele B group names.
`...` | Not used.

### Details

Allele A and allele B are merged into a `matrix` where first row hold the elements for allele A and the second elements for allele B.

### Value

Returns a `list` structure with the two groups `forward` and `reverse`, if the latter exists.
