Create Useful Summaries of the Portal Data
Download and generate summaries for the rodent, plant, ant, and weather data from the Portal Project. Portal is a long-term (and ongoing) experimental monitoring site in the Chihuahua desert. The raw data files can be found at < https://github.com/weecology/portaldata>.
Overview
The portalr package provides collection of basic functions to summarize the Portal project 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.
Installation
You can install portalr from CRAN with:
install.packages("portalr")
OR from github with:
# install.packages("devtools")devtools::install_github("weecology/portalr")
Examples
- Load all data tables from the PortalData GitHub repo:
data_tables <- load_rodent_data("repo")
- Download and generate summaries of rodent abundance and biomass:
download_observations(".")rodent_data <- abundance(".") # default grouping is by sampling periodrodent_biomass_by_plot <- biomass(".", level = "plot", type = "granivores",shape = "flat", time = "date")
- Retrieve weather data:
weatherdata <- weather("Monthly", ".")

Portal Data Repo
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.
