QGIS functions available from R

[erex]

A package provides an R interface to QGIS, some functions in C++.

The list of available functions >900. I've only tried one function.

remotes::install_github("paleolimbot/qgisprocess")
library(qgisprocess)
qgis_configure()
input <- sf::read_sf(system.file("shape/nc.shp", package = "sf"))
result <- qgis_run_algorithm(
  "native:buffer",
  INPUT = input,
  DISTANCE = 1,
  DISSOLVE = TRUE,
  .quiet = TRUE
)
output_sf <- sf::read_sf(qgis_output(result, "OUTPUT"))
plot(sf::st_geometry(output_sf))
plot(sf::st_geometry(input), add=TRUE)

Works on my Windows box (with sufficiently current version of QGIS (3.16.2)), don't know how much faff needed for other OSs
