Download and cache a file

Usage

cacheUrl(url, pkg = "pipette", update = FALSE, ask = FALSE, verbose = TRUE)

Arguments

url: character(1). Uniform Resource Locator (URL).
pkg: character(1). Package name.
update: logical(1). Call bfcneedsupdate internally to see if URL needs an update. Doesn't work reliably for all servers, so disabled by default.
ask: logical(1). Ask if package cache needs to be created or if file needs to be updated.
verbose: logical(1). Run the function with verbose output.

Value

character(1). Cached file path on disk.

Details

Caching requires BiocFileCache and tools packages to be installed. If BiocFileCache is not installed, URL will be downloaded as a temporary file instead.
