canberra {OmicsMarkeR} | R Documentation |
Calculates canberra distance between two vectors. In brief, the higher the canberra distance the greater the 'distance' between the two vectors (i.e. they are less similar).
canberra(x, y)
x |
numeric vector of ranks |
y |
numeric vector of ranks with compatible length to x |
Returns the canberra distance for the two vectors
The canberra_stability
function is used
internally to return the canberra metric.
