glottospace {glottospace}

Make glottodata spatial and generate language polygons from points.

Description

This function takes glottodata (either with or without metadata) and turns it into spatial points or polygons.

Usage

glottospace(glottodata, method = NULL, radius = NULL)

Arguments

glottodata

A glottodata table, or list of a glottodata table and metadata table(s)

method

Interpolation method, either "buffer" or "voronoi" (synonymous with "thiessen")

radius

In case interpolation method "buffer", the radius in km.

Value

A spatial version of glottodata. In case glottodata has metadata, only glottodata will be converted to spatial (but all metadata tables are kept). Object returned as sf object, or a list of which the first element is an sf object, depending on the input.

Examples

glottodata <- glottoget("demodata", meta = TRUE)

glottospacedata <- glottospace(glottodata, method = "voronoi")
