deGenes2by2Wilcox {maigesPack} | R Documentation |
This function takes an object of class maiges
and do
differential expression analysis for the genes onto dataset, comparing
only two samples, by the Wilcox (Mann-Withney) test.
deGenes2by2Wilcox(data=NULL, sLabelID=names(data@Slabels)[1], sTypeComp=NULL, doClust=TRUE, ...)
data |
object of class maiges . |
sLabelID |
character string giving the sample label ID to be used. |
sTypeComp |
list with character vectors specifying the two sample types to be compared. |
doClust |
logical indicating if the object generated from this analysis will be used for cluster analysis. Defaults to TRUE. |
... |
additional parameters for functions
t.test , wilcox.test or
bootstrapT . |
This function calculate Wilcox statistics and p-values for the test
comparing the equality of means using the function
wilcox.test
.
There another function to do parametric t test ,
deGenes2by2Ttest
, and another option of non-parametric
test doing bootstrap of t statistics, deGenes2by2BootT
.
The result of this function is an object of class
maigesDE
if doClust
if FALSE or of class
maigesDEcluster
if it is TRUE.
