Search layer names by pattern — wfs_find

A convenience wrapper around wfs_layers() that filters results with grep(). Useful when a service has dozens or hundreds of layers.

wfs_find_layers(
  base_url,
  pattern,
  driver = "auto",
  version = NULL,
  srs = NULL,
  ignore.case = TRUE
)

Arguments

base_url: Character. The service endpoint URL. Can be a raw URL or a GDAL-prefixed connection string (e.g. "WFS:https://...").
pattern: Character. A regular expression to match against layer names.
driver: Character. One of "auto", "WFS", "OAPIF", "ESRIJSON".
version: Character or NULL. WFS version.
srs: Character or NULL. Target SRS.
ignore.case: Logical. Passed to grep().

A character vector of matching layer names.
