BACarray {clac} | R Documentation |
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.
