set expression of the gene in genotype1 for a particular
sample to zero
Usage
setPerturbedLociToZero(object)
Arguments
object
a deseq data set column genotype1 in colData
(a brentlabRnaSeqSet also works)
Note
the error handling isn't good here yet -- it will error if there is a
perturbed loci that is not in the rownames of the object (eg, if it is filtered
due to low expression)
