calcWHPT_AB: Calculate abundance-weighted WHPT indices
In biotic: Calculation of Freshwater Biotic Indices

Description Usage Arguments Value Examples

Calculates WHPT abundance-weighted ASPT and N-taxa indices for invertebrate samples.

1	calcWHPT_AB(df, type = "num")

`df`	A dataframe containing list of taxa in first column, followed by columns of abundances with sample names in header row.
`type`	Indicates format of data. Options are "num" for numeric data, "log" for integer log abundance categories (1-5) or "alpha" for alphabetic abundance categories (A-E). Default value is "num".

A data frame consisting of columns of index values with samples in rows.

# calculate the WHPT abundance-weighted indices for the River Almond dataset
# data are numeric abundances, so type is "num" (can be omitted)

calcWHPT_AB(almond, "num")
