In GeneSelector: Stability and Aggregation of ranked gene lists

Description Slots Methods Author(s) See Also

Object returned by all implemented ranking methods (RankingTstat, RankingFC, RankingWelchT, RankingWilcoxon, RankingBaldiLong, RankingFoxDimmic, RankingLimma, RankingEbam, RankingWilcEbam, RankingSam, RankingShrinkageT, RankingSoftthresholdT, RankingPermutation).

x:: Gene expressionmatrix rows correspond to genes, columns to samples (arrays).
y:: A two-level factor of class labels.
statistic:: A numeric vector storing the test statistics.
ranking:: The ranking is determined via the statistic (normally via the size of absolute value). The lower the rank, the higher the magnitude of differential expression. There is no distinction of over- and underexpression.
pval:: The vector of p-values computed from statistic.
NA if p-values have not been computed.
type:: Type of the test (one of "unpaired", "paired", "onesample").
method:: Short name of the ranking method.

show: Use show(GeneRanking-object) for brief information.
summary: Use summary(GeneRanking-object) for a five-point-summary of statistics and p-values arranged as two-column table. The second column (p-values) are NA in the case that p-values have not been computed.
toplist: Use toplist(object, k=10) to get information about the top k=10 genes.
