Description Usage Arguments Details Value Note Author(s) See Also Examples

Constructor for class UniFilter allows to apply different unitest filters to class ExprTreeSet, i.e. to the expression level data.frame data.

UniFilter(unitest    = "t.test",
          foldchange = character(),
          prescall   = character(),
          unifilter  = character())

`unitest`	`"character"` vector describing parameters for `uniTest`.
`foldchange`	`"character"` vector describing parameters for `fcFilter`.
`prescall`	`"character"` vector describing parameters for `callFilter`.
`unifilter`	`"character"` vector describing parameters for `unitestFilter`.

The UniFilter constructor allows to apply the following unitest filters to class ExprTreeSet:

	`unitest`:	character vector c(type,alternative,correction.numperm,mu,paired,conflevel,varequ).
	`foldchange`:	character vector c(cutoff,direction).
	`prescall`:	character vector c(cutoff,samples,condition).
	`unifilter`:	character vector c(cutoff,variable).

An object of type "UniFilter"

Function UniFilter is used as constructor for class UniFilter so that the user need not know details for creating S4 classes.

## fill character vectors within constructor
unifltr <- UniFilter(unitest=c("t.test","two.sided","none",0,0.0,FALSE,0.95,TRUE),
                     foldchange=c(1.3,"both"),unifilter=c(0.1,"pval"))
str(unifltr)

## alternatively add character vectors as methods after creation of constructor
unifltr <- UniFilter()
fcFilter(unifltr) <- c(1.5,"both")
unitestFilter(unifltr) <- c(0.01,"pval")
str(unifltr)
