list_service_raster_fns: List Available Raster Funcitons

Description

This function returns the rasterFunctionInfos field of the ImageServer's metadata as a data.frame. If the field does not exist then an error is emitted.

Usage

list_service_raster_fns(
  x,
  arg = rlang::caller_arg(x),
  call = rlang::caller_call()
)

Value

a data.frame of the available raster functions.

Arguments

x

an ImageServer.

arg

An argument name in the current function.

call

The execution environment of a currently running function, e.g. call = caller_env(). The corresponding function call is retrieved and mentioned in error messages as the source of the error.

You only need to supply call when throwing a condition from a helper function which wouldn't be relevant to mention in the message.

Can also be NULL or a defused function call to respectively not display any call or hard-code a code to display.

For more information about error calls, see Including function calls in error messages.

Examples

if (FALSE) {
# use paste to avoid cran note
furl <- paste0(
  "https://di-usfsdata.img.arcgis.com/arcgis/rest/services",
  "/FIA_BIGMAP_2018_Species_Aboveground_Biomass/ImageServer"
)

service <- arc_open(furl)
raster_fns <- list_service_raster_fns(service)
head(raster_fns)
}
