Pretty formatting of p values

Pretty formatting of p values

formatPvalue(values, digits = 3, spaces = TRUE, includeP = TRUE)

Arguments

values

The p-values to format.

digits

The number of digits to round to. Numbers smaller than this number will be shown as <.001 or <.0001 etc.

spaces

Whether to include spaces between symbols, operators, and digits.

includeP

Whether to include the 'p' and '='-symbol in the results (the '<' symbol is always included).

Value

A formatted P value, roughly according to APA style guidelines. This means that the noZero function is used to remove the zero preceding the decimal point, and p values that would round to zero given the requested number of digits are shown as e.g. p<.001.
