varImportances: random forests based marker discovery

In tangchao7498/ICAS:

Description

Identifies 'markers' of SJ expression using OOB analysis. For each SJ, evaluates (using AUC) a classifier built on that SJ alone, to classify between two groups of cells.

Usage

varImportances(object, cells.1, cells.2, genes.use = NULL,
  print.bar = TRUE, NT = 1)

Arguments

object	ICASDataSet object
cells.1	Group 1 cells
cells.2	Group 2 cells
genes.use	SJs to test. Default is to use all SJs
print.bar	Print a progress bar once expression testing begins (uses pbapply to do this)
NT	cores for parallel (Currently only support roc test)

Value

Returns a 'predictive power' (abs(AUC-0.5)) ranked matrix of putative differentially expressed SJs.
