Description

Calculate gene scores on permutation data sets

Usage

1
2
genePermuteScore(DEscoreMat, DSscoreMat = NULL, method = c("linear", "quadratic", "rank"), 
                 DEweight = 0.5)

Arguments

DEscoreMat

normalized DE scores on permutation data sets.

DSscoreMat

normalized DS scores on permutation data sets.

method

one of the integration methods: linear, quadratic, or rank; default: linear.

DEweight

any number between 0 and 1 (included), the weight of differential expression scores (the weight for differential splice is (1-DEweight)).

Details

The integration methods including "linear", "quadratic", and "rank" are detailed in Wang and Cairns (2013). Here the rank method refers only to the method using data-set-specific ranks.

For DE-only analysis, just specify DEweight to be 1, and the DSscoreMat value can be NULL.

Value

A gene score matrix.
