Format p-values — format_p • formatstats

All functions in this package are deprecated. Please use the {cocoon} package instead.

format_p() inputs numeric vectors of p-values. Cutoffs can be set that format the values as less than the cutoffs (e.g., p < 0.001). The default output is APA formatted, but numbers of digits, cutoffs, leading zeros, and italics are all customizable.

Usage

format_p(
  x,
  digits = 3,
  pzero = FALSE,
  label = "p",
  italics = TRUE,
  type = "md"
)

Arguments

x: Number representing p-value
digits: Number of digits after the decimal for p-values, ranging between 1-5 (also controls cutoff for small p-values)
pzero: Logical indicator of whether to include leading zero for p-values
label: Character string for label before p value. Default is p. Set label = "" to return just the formatted p value with no label or operator (=, <, >)
italics: Logical for whether label should be italicized (p)
type: Type of formatting ("md" = markdown, "latex" = LaTeX)

Value

A character string that includes p and then the p-value formatted in Markdown or LaTeX. If p-value is below digits cutoff, p < cutoff is used.

Examples

format_p(0.001)
#> [1] "_p_ = .001"
# Round digits for p-values greater than cutoff
format_p(0.111, digits = 2)
#> [1] "_p_ = .11"
# Default cutoff is p < 0.001
format_p(0.0001)
#> [1] "_p_ < .001"
# Set cutoff with digits
format_p(0.0001, digits = 2)
#> [1] "_p_ < .01"
# Include leading zero
format_p(0.001, pzero = TRUE)
#> [1] "_p_ = 0.001"
# Return only Bayes factor value (no label)
format_p(0.001, label = "")
#> [1] ".001"
