Description Usage Arguments Details Author(s) Examples

Function to add expression data and its annotations to a gosummaries object.

1	add_expression.gosummaries(gosummaries, exp, annotation = NULL)

`gosummaries`	a gosummaries object
`exp`	an expression matrix, with row names corresponding to the names in the Gene_lists slot
`annotation`	a `data.frame` describing the samples, its row names should match with column names of `exp`

The data is added to the object in a "long" format so it would be directly usable by the ggplot2 based panel drawing functions panel_boxplot etc. For each component it produces a data frame with columns:

x : sample IDs for the x axis, their factor order is the same as on the columns of input matrix
y : expression values from the matrix
. . . : sample annotation columns from the annotation table that can be displayed on figure as colors.
