unitestFilter-methods {xps} | R Documentation |
This method initializes the Unitest Filter.
Applying an unitest such as the t.test
to two groups returns the p-value for the test
and the value of the t-statistic. The Unitest Filter allows to select only rows satisfying
e.g. a certain p-value as cutoff.
The Unitest Filter flags all rows with: flag = (variable <= cutoff)
Usage
unitestFilter(object)
unitestFilter(object, value)<-
object |
object of class UniFilter . |
value |
character vector c(cutoff, variable) . |
The method unitestFilter
initializes the following parameters:
cutoff : | the cutoff level for the filter. | |
variable : | variable="pval" (default): p-value. |
|
variable="stat" : univariate statistic. |
||
variable="padj" : optional adjusted p-value. |
||
variable="pcha" : optional p-value obtained by permutations. |
An initialized UniFilter
object.
