pvalue: Rounding criterion for p-values

In gcastella/statTools: Easier statistical analyses

Description

Rounding significant p-values to the first non-zero decimal number and non-significant to two decimal places.

Usage

pvalue(pval, show.sig.stars = FALSE, alpha = 0.05)

Arguments

pval	Vector or matrix of p-values to be rounded.
show.sig.stars	Default to FALSE. TRUE for displaying stars, dots or nothing depending on the significance of the p-value.
alpha	Default to 0.05. Threshold for significance.

Details

P-values below 0.00001 are displayed as "<0.00001". This is the default function for rounding p-values. In case of confusion when the rounding returns exactly the value alpha, another decimal place is given. This can be changed in options("p.value.rounding"), with is a list where the first element is the name of the function as a string, and the other elements, the parameters to pass to this function.

Value

An object with the same class of pval, with all the p-values properly rounded and returned as strings.
