Installation

You can install addSchwartzGeohashPM from GitHub with:

# install.packages("remotes")
remotes::install_github("degauss-org/schwartzGeohashPM")

s3 downloads

This package utilizes the s3 package. Users can pass arguments for s3::s3_get_files to schwartzGeohashPM::add_schwartz_pollutants. This is especially useful for specifying the local path where s3 files will be downloaded onto the user's local machine, via the download_folder argument. The download folder can also be specified by setting options.

options(s3.download_folder = /path/to/folder/s3_downloads)

Example

reticulate::use_condaenv("r-s3", required = TRUE)

library(schwartzGeohashPM)

d <- tibble::tribble(
      ~id,         ~lat,    ~lon, ~site_index,      ~sitecode,  ~start_date,    ~end_date,
