A simple function to associated p-values with symbols

Source: R/signifSymbols.R

The signifSymbols function takes one vector of p-values and returns a vector of symbols that correspond to thresholds that can be set. Default thresholds values and symbols are the most common ones.

signifSymbols(
  pvalue,
  thresholds = c(0.1, 0.05, 0.01, 0.001),
  symbols = c(".", "*", "**", "***"),
  notsignif = "n.s."
)

Arguments

pvalue

a p-value for which a symbol is requested.
thresholds

the threshold values that define category to which symbols are assigned.
symbols

list of symbols.
notsignif

symbols for non significant p-value.

Examples

signifSymbols(.012)

#> [1] "*"
signifSymbols(.008)

#> [1] "**"
lapply(c(.2, .08, .04, .008, 0.0001), signifSymbols)

#> [[1]]
#> [1] "n.s."
#> 
#> [[2]]
#> [1] "."
#> 
#> [[3]]
#> [1] "*"
#> 
#> [[4]]
#> [1] "**"
#> 
#> [[5]]
#> [1] "***"
