cf_equal function

Identify Fossils with equal min and max age

Removes or flags records with equal minimum and maximum age.

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

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.

Returns

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 .

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")
