The portalr package provides collection of basic functions to summarize the Portal porject data on rodents, plants, ants, and weather at our long-term field site in the Chihuahuan Desert. The data begin in 1977 and are continuously updated today. There are functions to summarize rodent abundance, biomass, or energy and by site, plot, or treatment type. There are functions to summarize the weather data collected from our automated weather stations and plant data that is collected each summer and fall.
You can install portalr from CRAN with:
OR from github with:
# install.packages("devtools") devtools::install_github("weecology/portalr")
- Load all data tables from the PortalData GitHub repo:
data_tables <- load_data("repo")
- Download and generate summaries of rodent abundance and biomass:
download_observations(".") rodent_data <- abundance(".") # default grouping is by sampling period rodent_biomass_by_plot <- biomass(".", level = "plot", type = "granivores", shape = "flat", time = "date")
- Retrieve weather data:
weatherdata <- weather("Monthly", ".")

The data repo contains useful details for issues with data collection, and background on why we handle them the way we do. Of course, it also contains the raw data, if you would like to create more complex data summaries than what is provided here.
