In rnaSeqMap: rnaSeq secondary analyses

Description Usage Arguments Value Author(s) Examples

Set of functions to operate on NucleotideDistr objects.

averageND calculates the mean for samples, sumND adds up selected samples' distributions, combineND adds two objects with the same size of distribution matrix, log2ND transforms all numeric data in the object into log space.

averageND(nd, exps);
sumND(nd, exps);
combineND(nd1, nd2);
log2ND(nd);

`nd, nd1, nd2`	`NucleotideDistr` objects
`exps`	a pair of numbers of samples in the experiment

NucleotideDistr object of the same type as input objects
