Examples

# \donttest{
  testfolder <- system.file("testdata/shapes/Portland_neighborhoods", package = "EJAM")
  testshape <- shapefile_from_folder(testfolder)
#> Warning: No basename found -- returning NULL
#> Warning: need vector of full paths and filenames that must include all these extensions .shp, .shx, .dbf, and .prj 

  testpaths <- shapefile_filepaths_from_folder(testfolder)
  testshape <- shapefile_from_filepaths(testpaths)
#> Warning: No basename found -- returning NULL
#> Warning: need vector of full paths and filenames that must include all these extensions .shp, .shx, .dbf, and .prj 

  ## if interactive(), R user can point to right folder or select the right set of files:
  # testshape <- shapefile_from_filepaths()
  # testshape <- shapefile_from_folder()

  x <- get_blockpoints_in_shape(testshape)
#> Error in `[.data.frame`(x, i): undefined columns selected
  leaflet::leaflet(x$polys) %>% leaflet::addTiles() %>% leaflet::addPolygons(color = "blue")
#> Error in leaflet::leaflet(x$polys) %>% leaflet::addTiles() %>% leaflet::addPolygons(color = "blue"): could not find function "%>%"
  DT::datatable(out$results_bysite)
#> Error: object 'out' not found
