getResults: Get significance results according to a stage-wise analysis.
In stageR: stageR: stage-wise analysis of high throughput gene expression data in R

Description Usage Arguments Details Value References Examples

This functions returns a matrix that indicates whether a specific feature is significant for a specific hypothesis of interest according to a stage-wise analysis. The function is not applicable to transcript-level analysis.

getResults(object, ...)

## S4 method for signature 'stageR'
getResults(object)

object

an object of the stageRClass class.

The FDR adjusted screening hypothesis p-values are compared to the alpha level specified. The FWER adjusted confirmation stage p-values are compared to the adjusted significance level from the screening stage.

A logical matrix with rows corresponding to genes and columns corresponding to contrasts, where the first column represents the screening stage on the aggregated p-values. A 0 represents a non-significant test, a 1 represents a significant test according to the stage-wise analysis.
