MinMaxMST {cati} | R Documentation |
Ratio of the shortest distance to the longest distance in a minimum spanning tree.
MinMaxMST(traits, gower.dist = TRUE, scale.tr = TRUE, method.dist = "euclidian")
traits |
Traits matrix (traits in column) |
gower.dist |
Calculate gower distance using the function gowdis from package FD. |
scale.tr |
Does traits need to be scale before multi-traits metric calculation? Only use when gower.dist = FALSE. Default is yes. |
method.dist |
Method to calculate the distance in case of multi-traits metric (function dist). Only use when gower.dist = FALSE. Default is euclidian. |
The value of the ratio of the shortest distance to the longest distance in a minimum spanning tree.
