Species Maximum Standardization
Standardizes a community data.frame by dividing the abundance of each species by the maximum value obtained for that species.
spcmax(comm)
comm |
community data.frame (samples as rows, species as columns) |
This is a simple standardization to make each species abundance scaled from 0 to 1, essentially relativizing abundance by species and making each species equal in the calculation of distance or dissimilarity or other analyses.
A data.frame of standardized community data.
