Returns gene sets in a cell of the results.table.

Description

pickOut returns a character vector with the Gene Ontology ID's of the gene sets with a particular significance profile for a certain contrast (the gene sets in one cell of the results.table of an mvGST object).

Usage

1
pickOut(mvgst, row, col = 1)

Arguments

mvgst

A mvGST object. mvGST$results.table must not be NULL.

row

The row of the desired profile.

col

The column of the desire contrast. Column refers to the levels of Var2, if Var2 was used. It is the number of the column after the 1, 0, -1 columns that show the profiles. Default value is 1.

Value

A data frame containing the ID's of the gene sets in the given row and column along with the GO descriptions of each gene set and the adjusted p-values for each contrast tested.
