Description

The three objects are: datcenFarkas: methylation data for cervix samples (arcsine-transformed beta values); respFarkas: binary response;and CpGannFarkas: annotation of probes according to location

Format

• datcenFarkas: data frame [1:40000,1:37]

• respfarkas: Factor w/ 2 levels "Normal","Precursor"

• CpGannFarkas: Factor w/ 6 levels "CpG-Island", "North-Shelf", "South-Shelf", "North-Shore", "South-Shore", "Distant"

Details

This data is used for illustration in the statistical paper below.

Value

Three R objects, i.e. a matrix contains methylation data, a vector contains binary responses and an annotation matrix.
