Helper function to download Census data

Description

Helper function to download Census data

Usage

load_tiger(
  url,
  refresh = getOption("tigris_refresh", FALSE),
  tigris_type = NULL,
  class = getOption("tigris_class", "sf"),
  progress_bar = TRUE,
  keep_zipped_shapefile = FALSE,
  filter_by = NULL
)

Arguments

`url`	URL for zipped shapefile in TIGER database (constructed in calling function).
`refresh`	Whether to re-download shapefiles if cached. Defaults to value of the global option "tigris_refresh" if that option is, and FALSE if not. This will override the behavior set in "tigris_refresh" option if a value (TRUE or FALSE) is provided.
`tigris_type`	Added as an attribute to return object (used internally).
`class`	Class of return object. Must be one of "sf" (the default) or "sp".
`progress_bar`	If set to FALSE, do not display download progress bar (helpful for R Markdown documents). Defaults to TRUE.
`keep_zipped_shapefile`	If set to TRUE, do not delete zipped shapefile (stored in temporary directory or TIGRIS_CACHE_DIR depending on the configuration of global option "tigris_use_cache"). Defaults to FALSE.
`filter_by`	Geometry used to filter the output returned by the function. Can be an sf object, an object of class `bbox`, or a length-4 vector of format `c(xmin, ymin, xmax, ymax)` that can be converted to a bbox. Geometries that intersect the input to `filter_by` will be returned.
