ASCI

Marcus W. Beck (maintainer), [e-mail], Susanna Theroux, [e-mail], Quynh-Thi Ho, [e-mail], John Van Sickle

R package materials to calculate the Algal Stream Condition Index (ASCI) based on O/E and pMMI scores using diatom, soft-bodied algae, or a hybrid appproach.

Installation

Install the package as follows:

install.packages('devtools')
library(devtools)
install_github('SCCWRP/ASCI')
library(ASCI)

Usage

The sample files demo_algae_tax and demo_station are included to demonstrate the correct formats for the input data. The demo_algae_tax file is a data.frame of taxonomic data in long format (one row per sample). The demo_station file is a data.frame of GIS predictors in wide format, one row per station. See the help files for more information (e.g., ?demo_algae_tax). Also see the help file for chkinp() and calcgis() for requirements of each file to work with the ASCI.

devtools::load_all()

head(demo_algae_tax)
head(demo_station)

The output is in a wide format.

demo_results <- ASCI(demo_algae_tax, demo_station)
demo_results
