cf_equal: Identify Fossils with equal min and max age

Description

Removes or flags records with equal minimum and maximum age.

Usage

cf_equal(
  x,
  min_age = "min_ma",
  max_age = "max_ma",
  value = "clean",
  verbose = TRUE
)

Value

Depending on the ‘value’ argument, either a data.frame

containing the records considered correct by the test (“clean”) or a logical vector (“flagged”), with TRUE = test passed and FALSE = test failed/potentially problematic . Default = “clean”.

Arguments

x

data.frame. Containing fossil records with taxon names, ages, and geographic coordinates.

min_age

character string. The column with the minimum age. Default = “min_ma”.

max_age

character string. The column with the maximum age. Default = “max_ma”.

value

character string. Defining the output value. See value.

verbose

logical. If TRUE reports the name of the test and the number of records flagged.

Examples

minages <- runif(n = 10, min = 0.1, max = 25)
x <- data.frame(species = letters[1:10], 
                min_ma = minages, 
                max_ma = minages + runif(n = 10, min = 0, max = 10))
x <- rbind(x, data.frame(species = "z", 
                min_ma = 5, 
                max_ma = 5))
                
cf_equal(x, value = "flagged")
