nEQR: nEQR
In trtcrd/BBI: Benthic Biotic Indices Calculation from Composition Data

Description Usage Arguments Value Examples

The nEQR function compute the normalized Ecological Quality Ratio (nEQR).

1	nEQR(data)

data

A data frame containing samples as rows and BBI values as columns

Function nEQR returns a list containing :

`nEQR`	The nEQR value.
`nEQR_class`	The dicrete ecological quality assessment.

## Loading the exemple data
data("metab")
data("morpho")
## Computing BBI indices
BI_metab <- BBI(metab)
BI_morpho <- BBI(morpho)
## And then computing nEQR
eqr <- nEQR(BI_metab$BBI)
## print nEQR values
eqr$nEQR
## print discrete status
eqr$nEQRclass
