Description

Initialize a RegspliceResults object, which will contain the results of the regsplice analysis.

Usage

1

Arguments

rs_data

RegspliceData object. This should contain gene IDs in a column named gene_IDs in the row meta-data, which can be accessed with the accessor function rowData.

Details

Creates a RegspliceResults object containing gene names only. This object will subsequently be populated using the functions fitRegMultiple, fitNullMultiple, fitFullMultiple, and LRTests.

Previous step: Calculate limma-voom transformation and weights with runVoom. Next step: Fit models with fitRegMultiple, fitNullMultiple, and fitFullMultiple.

Value

Returns a RegspliceResults object containing gene IDs only.
