In rmapshaper: Client for 'mapshaper' for 'Geospatial' Operations

Apply a mapshaper command string to a geojson object

Description

Apply a mapshaper command string to a geojson object

Usage

apply_mapshaper_commands(
  data,
  command,
  force_FC = TRUE,
  sys = FALSE,
  sys_mem = 8
)

Arguments

data	geojson object or path to geojson file. If a file path, sys must be true
command	valid mapshaper command string
force_FC	should the output be forced to be a FeatureCollection (or Spatial*DataFrame) even if there are no attributes? Default TRUE. FeatureCollections are more compatible with rgdal::readOGR and geojsonio::geojson_sp. If FALSE and there are no attributes associated with the geometries, a GeometryCollection (or Spatial object with no dataframe) will be output.
sys	Should the system mapshaper be used instead of the bundled mapshaper? Gives better performance on large files. Requires the mapshaper node package to be installed and on the PATH.
sys_mem	How much memory (in GB) should be allocated if using the system mapshaper (sys = TRUE)? Default 8. Ignored if sys = FALSE.

Value

geojson
