Barcoding Gap Calculation
Description
Calculation of DNA barcoding gap. Besides K2P distance, raw distance and euclidean could also be used for calculation DNA barcoding gap.
Usage
barcoding.gap(ref, dist = dist)
Arguments
ref |
object of class "DNAbin" used as a reference dataset, which contains taxon information. |
dist |
a character string which takes one of ("raw","K80","euclidean"). |
Value
a list indicates the summary statistics of interspecific and intraspecific genetic distance, such as k2P distance.
Note
the current version of the function can only be used for protein-coding barcodes, such as, COI. The futuren version may incorporate calculation for non-coding barcodes,for instance, ITS1, ITS2.
