object of class maiges to be used to
functionally classify gene groups stored in GeneGrps slot.
gNameID
character string specifying identification of gene
label to be used.
sLabelID
idem to the previous argument for identification of
sample label.
samples
a list with character vectors specifying the groups
that must be compared.
usePaths
logical specifying if the pathways given in
Paths slot must also be used, defaults to FALSE.
cutExp
real number specifying the cutoff for expression levels
(to discretise the expression)
adjP
character string giving the type of p-value
adjustment. May be 'Bonferroni', 'Holm', 'Hochberg', 'SidakSS',
'SidakSD', 'BH', 'BY' or 'none'. Defaults to 'none'. See function
mt.rawp2adjp in package multtest for more details.
cutPhiper
p-value cutoff to select significant gene groups.
Details
If the argument samples is NULL, all types defined by the
sample label given by sLabelID are used. It is possible to use
the plot.maigesActMod and
image.maigesActMod to display the results of this
analysis. This function is based in the method proposed by
Segal et al. (2004).
Value
The result of this function is an object of class maigesActMod.
## Loading a little dataset
data(gastro)
## Doing functional classification of gene groups for 'Tissue' sample label
gastro.mod = activeMod(gastro.summ, sLabelID="Tissue", cutExp=1,
cutPhiper=0.05)
## Doing functional classification of gene groups together with the
## networks given by Paths slot for 'Tissue' sample label. Also we are
## using a cuttoff for p-value of hipergeometric test as 0.1
gastro.mod = activeMod(gastro.summ, sLabelID="Tissue", cutExp=1,
cutPhiper=0.1, usePaths=TRUE)
