adjPval {maanova} | R Documentation |
This function takes a result object from matest
and calculate the FDR adjusted P values. The new P values will be
appended to the input object as additional fields. It has four
options; "stepup" (Hochberg and Benjamini, 1990), "adaptive" (Benjamini and Hochberg, 2000), "stepdown" (Westfall and Young, 1993) and "jsFDR" (Storey,
2002). "jsFDR" option uses 'qvalue' package by John Storey and user suppose
to install 'qvalue' package before using this option. There is no default
option, thus you need to specify one option.
adjPval(matestobj, method=c("stepup","adaptive", "stepdown", "jsFDR"))
