AggregateSimple {GeneSelector} | R Documentation

## Simple aggregation of repeated rankings

### Description

All obtained rankings are aggregated by a genewise summary `measure`.

### Usage

      AggregateSimple(RR, measure = c("mode", "mean", "trimmed.mean", "median", "quantile"), q=NULL, trim = NULL)

### Arguments

`RR` | An object of class `RepeatedRanking`
`measure` | The statistic to be used as basis for the aggregated ranking. mode The rank occuring most frequently. If several ranks occur equally often, the lowest one is used. mean The mean of the ranks. trimmed.mean The trimmed mean of the ranks, i.e. the mean resulting when throwing away the `trim`*100 percent most extreme observations at both tails. median The median of the ranks. quantile The `q`-quantile, `0 <= q <= 1`, of the ranks.
`q` | Only specified if `measure="quantile"`.
`trim` | s. `trimmed.mean`.

### Value

An object of class AggregatedRanking.

### Examples

    ## Load toy gene expression data
    data(toydata)
    ### class labels
    yy <- toydata[1,]
    ### gene expression
    xx <- toydata[-1,]
    ### run RankingTstat
    ordT <- RankingTstat(xx, yy, type="unpaired")
    ### Generate Leave-one-out Foldmatrix
    loo <- GenerateFoldMatrix(y = yy, k=1)
    ### Get all rankings
    loor_ordT <- RepeatRanking(ordT, loo)
    ### aggregate rankings
    agg_simple_ordT <- AggregateSimple(loor_ordT, measure ="mean")
    toplist(agg_simple_ordT)
