signed_url: Share Amazon CloudFront file via presigned url

In pbreheny/breheny: Miscellaneous Functions

Share Amazon CloudFront file via presigned url

Description

Shares Amazon CloudFront file. Currently only set up for teaching files; see bin/signed-url.

Usage

signed_url(file, out = stdout(), expiration = 365, r)

Arguments

file	Character vector of files to share. If path is included, it will be included in the download script save location.
out	A connection object or character string, as in ⁠[writeLines()]⁠, to which R commands are to be saved. If nothing is supplied, output is to console.
expiration	How long until URLs expire (in days)? Numeric. Default: 365.
r	Output R code (as opposed to link)? By default, the function will return links if out=stdout() and R code if out otherwise. However, this can be overridden by explicitly setting r to be TRUE or FALSE.

Value

Either a url or R script. The latter is particularly useful for batch downloads and specifying file save paths.
