mvGST (version 1.6.0)

go2Profile: Creates tables showing profiles of specific gene sets.

Description

Creates tables similar to the results tables of an mvGST object except for one gene set at a time. For each gene set selected, a table is produced with a single one and all zeroes in each column.

Usage

go2Profile(names, object)

Arguments

names

A character vector with the names, ID's, of the gene sets of interest. If the gene set names were not provided by the user, then this should be the GO ID's of the gene sets of interest.

object

A mvGST object with a final results.table.

Value

A list of matrices. Each matrix has possible profiles as the row names and contrasts as the column names. Ones in the appropriate cells showing which profile the gene set fit for each contrast and zeroes elsewhere. The names of the list are the names, or ID's, provided.
