Usage
bmwp_ind(dataset, store = FALSE, dec_c = ".", verbose = FALSE)
Value
This function returns a list with the following components:
Ibmwp_n
The numerical BMWP and ASPT index (Armitage et al. 1983).
Ibmwp_c
The BMWP and ASPT water quality class (Armitage et al. 1983).
Arguments
dataset
A data.frame obtained from read_data.
store
A logical value indicating if the user want to store the results in a file.
dec_c
A character used for decimal separator on results file.

Details
The Biological Monitoring Working Party (BMWP) was set up in 1976. Its terms of reference were to recommend a system which could be used to assess the biological status of a river, and which would be suitable for presenting a broad picture of one aspect of the biological condition of rivers in the UK. Identification to family is sufficient to calculate the BMWP score. The average score per taxon (ASPT) is calculated by dividing the score by the total number of scoring taxa (Armitage et al. 1983).
