Round p-value

Source: R/misc.R
round_p.Rd

If p-value is <= 0.001, returns ".001" else returns p-value rounded to the specified number of digits, optionally including relation sign ("<" or "=").

Usage

round_p(
  values,
  include.rel = 1,
  digits = 3,
  strip.lead.zeros = TRUE,
  replace.very.small = 0.001
)

Arguments

values

a vector of p-values

include.rel

include relation sign

digits

a number of decimal digits

strip.lead.zeros

remove zero before decimal point

replace.very.small

replace values lower than this criteria (NULL to keep values as is)

Value

A character vector of formatted p-values, including the requested relation signs and small-value threshold notation.

Examples

p_values <- c(0.025, 0.0001, 0.001, 0.568)
round_p(p_values)
#> [1] "= .025" "< .001" "< .001" "= .568"
round_p(p_values, digits = 2)
#> [1] "= .03"  "< .001" "< .001" "= .57" 
round_p(p_values, include.rel = FALSE)
#> [1] ".025"   "< .001" "< .001" ".568"  
round_p(p_values, include.rel = FALSE, strip.lead.zeros = FALSE)
#> [1] "0.025"   "< 0.001" "< 0.001" "0.568"  
round_p(p_values, include.rel = FALSE, strip.lead.zeros = FALSE, replace.very.small = 0.01)
#> [1] "0.025"  "< 0.01" "< 0.01" "0.568"
