The goal of azmetr is to provide programmatic access to the Arizona Meteorological Network (AZMet) API in R.
Installation
You can install the development version of azmetr from r-universe:
install.packages('azmetr', repos = c('https://uace-azmet.r-universe.dev', 'https://cloud.r-project.org'))Alternatively, you can install a development version directly from GitHub with the remotes package:
# install.packages("remotes")
remotes::install_github("uace-azmet/azmetr")Example
For the most recent data from all stations, run functions without any arguments:
library(azmetr)
az_15min()
az_daily()
az_heat()
az_hourly()
az_lw15min()
az_lwdaily()Because azmetr uses the httr2 package to handle API requests, you can wrap any azmetr function with with_verbosity() to get more detailed logging of the actually HTTP requests and response headers. For example:
httr2::with_verbosity(az_daily())
