exampleCMAP: Generate example NChannelSets
In gCMAPWeb: A web interface for gene-set enrichment analyses

Description Usage Arguments Details Value Author(s) Examples

This function generates NChannelSets from randomly selected gene idenfiers and scores. Scores of the first (simulated) sample will be shifted up by the amount specified by the 'add' parameter for the first 50 genes and down by the same amount for genes 51-100.

1 2	exampleCMAP(universe = "org.Hs.eg.db", idType = "ENTREZID", rows = 1000, cols = 20, seed = 123, add = 3)

`universe`	character, the name of an available annotation package. Default=org.Hs.eg.db
`idType`	character, a valid identifier type supported by the selected annotation package. Default=ENTREZID
`rows`	integer, the number of genes to sample. Default=1000
`cols`	integer, the number of samples to generate. Default=20
`seed`	numeric, seed for the random number generator. Default=123
`add`	numeric, score shift for scores in the first sample column. Scores for genes 1-50 will be shifted up, those for genes 51-100 down.

This function is mainly intented for testing purposes.

NChannelSet with simulated scores.
