Install JTS Topology Suite from Latest GitHub Release

Downloads JTS JAR files to user data directory using utils::download.file(..., mode="wb").

install_jts(
  url = NULL,
  javadoc = FALSE,
  sources = FALSE,
  testbuilder = TRUE,
  overwrite = FALSE,
  ...
)

Arguments

url: Optional: custom URL or path to JAR file
javadoc: Download "Javadoc" JAR? Default: FALSE
sources: Download "sources" JAR? Default: FALSE
testbuilder: Download JTS Test Builder JAR? Default: TRUE
overwrite: Overwrite existing JAR file (if present)? Default FALSE
...: additional arguments passed to utils::download.file() (e.g. quiet, method)

Value

Downloads and installs JAR files to user data directory (invisibly returns result). After running this function, the JAR files will be automatically loaded when the package is attached.

Details

JAR files are stored in a platform-specific user data directory as determined by tools::R_user_dir("rjts", which = "data"), which respects R_USER_DATA_DIR, XDG_DATA_HOME, and platform defaults. This avoids the need to bundle JAR files in the package or re-install the package after downloading JARs.

Examples

if (FALSE) { # \dontrun{
install_jts()
} # }
