### Details

`LogRatio, Chromosome` and `PosOrder` are compulsory.

### Value

Objects `profileCGH` and `profileChr` are composed of a list with the first element `profileValues` which is a `data.frame` with the following columns names:

`LogRatio` | Test over Reference log-ratio.
`PosOrder` | The rank position of each clone on the genome.
`PosBase` | The base position of each clone on the genome.
`Chromosome` | Chromosome name.
