aldex.kw: Calculate the Kruskal-Wallis test and glm ANOVA statistics

In ALDEx2: Analysis Of Differential Abundance Taking Sample Variation Into Account

Description

aldex.kw calculates the expected values of the Kruskal-Wallis test and a glm ANOVA on the data returned by aldex.clr.

Usage

aldex.kw(clr, useMC = FALSE, verbose = FALSE)

Arguments

clr	An ALDEx2 object. The output of aldex.clr.
useMC	Toggles whether to use multi-core.
verbose	A boolean. Toggles whether to print diagnostic information while running. Useful for debugging errors on large datasets. Applies to effect = TRUE.

Value

Returns a data.frame with the following information:

kw.ep	a vector containing the expected p-value of the Kruskal-Wallis test for each feature
kw.eBH	a vector containing the corresponding expected value of the Benjamini-Hochberg corrected p-value for each feature
glm.ep	a vector containing the expected p-value of the glm ANOVA for each feature
glm.eBH	a vector containing the corresponding expected value of the Benjamini-Hochberg corrected p-value for each feature
