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 )
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. |
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”.
