Pretty formatting of p values
formatPvalue(values, digits = 3, spaces = TRUE, includeP = TRUE)
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). |
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.
formatPvalue(cor.test(mtcars$mpg, mtcars$disp)$p.value); #> [1] "p < .001" formatPvalue(cor.test(mtcars$drat, mtcars$qsec)$p.value); #> [1] "p = .62"
