planscorer offers an R interface to PlanScore.org’s API.
You can install the development version of planscorer from GitHub with:
# install.packages('remotes')

To use planscorer, you must have an API key from PlanScore. Otherwise, you will get a 403 forbidden error.
To get a key, follow the instructions here.
Once you have a key, use ps_set_key('your_key'). Optionally use ps_set_key('your_key', install = TRUE) to allow your key to be available across sessions.
With a file, you can upload using the ps_upload_file() option:
library(planscorer)
## basic example code
file <- system.file('extdata/null-plan-incumbency.geojson', package = 'planscorer')
links <- ps_upload_file(file)
#> ℹ Using single-step upload.
