AtlasRDF (version 1.8.0)

drawHeatMapForAtlasExperiment: Produce a heatmap of differentially expressed genes vs conditions for an Atlas experiment.

Description

Draws a heatmap of genes that are differentially expressed beyond a given t stat signficance against conditions they are diff expressed for for a given Atlas experiment.

Usage

drawHeatMapForAtlasExperiment(experimentid, tstatsignificance = 5, numoffactorsdiffexpressedacross = 1, endpoint = "http://www.ebi.ac.uk/rdf/services/atlas/sparql")

Arguments

experimentid
Atlas experiment ID which is to be visualized
tstatsignificance
The significance beyond which a gene should be included for visualisation. A significance value of '5' will only include genes with a t-stat of >= 5 or
numoffactorsdiffexpressedacross
Draw only genes which are differentially expressed across this number of specified factors (default is 1)
endpoint
SPARQL endpoint to query data from. Default value is the live Atlas SPARQL endpoint but this can be overidden.

Value

matrix of gene names with t-statistics for level of differential expression for each factor (one factor per column)

Examples
