A list containing an example CGH BAC array data for package clac
data(BACarray)
BACarray is a list of four components:
| NormalArray | a numeric matrix consisting of 2270 rows and 3 columns |
| DiseaseArray | a numeric matrix consisting of 2270 rows and 4 columns |
| chromosome | a numeric vector of length 2270 |
| nucposition | a numeric vector of length 2270 |
In NormalArray and DiseaseArray, each column corresponds to
one CGH array, and each row corresponds to one gene/clone. The value of each entry is the log fluorescence
ratio resulted from the CGH experiment. The order of the genes/clones in the rows is the same as the order of the
genes/clones on the genome. chromosome and nucposition provide chromosome number and nucleotide
position for each gene/clone.
