find_layer(ids, index = NULL, layer_categories = NULL, max_depth = 20)

Arguments

ids

Either the UUIDs or the identifiers resources from an idaifield_...-list as returned by get_idaifield_docs(), idf_query(), idf_index_query() or idf_json_query().

index

Examples

if (FALSE) { # \dontrun{
conn <- connect_idaifield(pwd = "hallo", project = "rtest")

 # For a nested Find:
index[which(index$identifier == "Befund_1_InschriftAufMünze"), ]
find_layer("Befund_1_InschriftAufMünze", index)

# For all resources:
find_layer(index$identifier, index)
