fm_safe_sp: Check for potential 'sp' version compatibility issues

In fmesher: Triangle Meshes and Related Geometry Tools

Check for potential sp version compatibility issues

Description

Loads the sp package with requireNamespace("sp", quietly = TRUE), and checks and optionally sets the sp evolution status flag if rgdal is unavailable. This function is only needed for backwards compatibility with sp versions before 2.0-0.

Usage

fm_safe_sp(quietly = FALSE, force = FALSE, minimum_version = "1.4-5")

Arguments

quietly	logical; if TRUE, prints diagnostic messages. Default FALSE
force	logical; If rgdal is unavailable and evolution status is less that 2L, return FALSE if force is FALSE. If force is TRUE, return TRUE if the package configuration is safe, potentially after forcing the evolution status to 2L. Default FALSE
minimum_version	character; the minimum required sp version. Default 1.4-5 (should always match the requirement in the package DESCRIPTION)

Value

Returns (invisibly) FALSE if a potential issue is detected, and give a message if quietly is FALSE. Otherwise returns TRUE

Examples

if (fm_safe_sp()) {
  # Run sp dependent calculations
}
