Download Asymmetric and Symmetric SAM indices — download_asymsam

Deprecated. The upstream API for the Asymmetric and Symmetric SAM indices is no longer available. These functions now return NULL with a warning.

Usage

download_asymsam_monthly(use_cache = FALSE, file = NULL)

download_asymsam_daily(use_cache = FALSE, file = NULL)

Arguments

use_cache: logical option to save and load from cache. If `TRUE`, results will be cached in memory if `file` is `NULL` or on disk if `file` is not `NULL`.
file: optional character with the full path of a file to save the data. If `cache` is `FALSE` but `file` is not `NULL`, the results will be downloaded from the internet and saved on disk.

Value

NULL (invisibly). A warning is issued.
