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.

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”.

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))
