In jjvanderwal/ALA4R: Atlas of Living Australia (ALA) data and resources in R

Description

Get or set configuration options that control ALA4R behaviour

Usage

ala_config(...)

ala_reasons()

Arguments

...

Options can be defined using name=value. Valid options are: reset: ala_config("reset") will reset the options to their default values caching string: caching can be "on" (results will be cached, and any cached results will be re-used), "refresh" (cached results will be refreshed and the new results stored in the cache), or "off" (no caching, default). cache_directory string: the directory to use for the cache. By default this is a temporary directory, which means that results will only be cached within an R session and cleared automatically when the user exits R. The user may wish to set this to a non-temporary directory for caching across sessions. The directory must exist on the file system. verbose logical: should ALA4R give verbose output to assist debugging? (default=FALSE) warn_on_empty logical: should a warning be issued if a request returns an empty result set? (default=FALSE) user_agent string: the user-agent string used with all web requests to the ALA servers. Default = "ALA4R" with version number, R version and date and user platform download_reason_id numeric or string: the "download reason" required by some ALA services, either as a numeric ID (currently 0–11) or a string (see ala_reasons() for a list of valid ID codes and names). By default this is NA. Some ALA services require a valid download_reason_id code, either specified here or directly to the associated R function. base_url_spatial string: the base url for spatial web services (default="http://spatial.ala.org.au/ws/") base_url_bie string: the base url for BIE web services (default="http://bie.ala.org.au/ws/") base_url_biocache string: the base url for biocache web services (default="http://biocache.ala.org.au/ws/") base_url_alaspatial string: the base url for older ALA spatial services (default="http://spatial.ala.org.au/alaspatial/ws/")

Value

For ala_config(), a list of all options. When ala_config(...) is called with arguments, nothing is returned but the configuration is set.
