Gets the physical position, log-intensities and log-ratios of chip effects for two arrays of units on a certain chromosome.
# S3 method for ChipEffectSet
getXAM(this, other, chromosome, units=NULL, ..., verbose=FALSE)
Returns a Nx3 matrix where N is the number of units returned. The names of the columns are X (physical position in a given chromosome), A (log-intensities) and M (log-ratios). The names of the rows are the unit indices (as indexed by the CDF).
Note: The rows are ordered according to chromosomal position.
