sfhelpers

Purpose

sfhelpers is a R package including functions helping to run routines related primarily to simple features (sf) , but also to spatial objects of other classes / packages ( stars, terra ). sfhelpers is motivated by multiple requests for code or advice related to sf. By publishing sfhelpers I hope to at least partly satisfy these demands. sfhelpers is still very much in the development phase; it may or may not go any further. Suggestions are welcome.

Installation

# install package remotes if not yet installed
# install.packages("remotes")

# install fast from GitHub without vignettes (not recommended)
# remotes::install_github("a-benini/sfhelpers")

# recommended: installation from GitHub including vignettes:
remotes::install_github(
  "a-benini/sfhelpers",
  build_vignettes = TRUE,
  dependencies = TRUE
  )

Usage

library(sfhelpers)

Usage Example

sfhelpers::st_or() is a sf equivalent of QGIS Union. st_or() returns a geometry set containing overlapping and non-overlapping parts of two input sf objects (or sfcs).

library(sf)
library(sfhelpers)

# the two included demo sf-objects have partly identically named attribute columns
st_agr(poly_1)
st_agr(poly_2)

# st_or() suffixes by default originally identically named attribute columns
st_or(x = poly_1, y = poly_2) %>% st_drop_geometry()

st_or(poly_1, poly_2) %>% plot()

For the rest of the functions included in sfhelpers see here.
