retry

Quoted expression to run, i.e., <code>quote(...)</code>

expr

The environment in which to evaluate the quoted expression, default
to <code>parent.frame(1)</code>

envir

Numeric. The maximum number of retries.

retries

Numeric &gt; 1.0. The delay between
successive retries will be <code>runif(1, min = 0, max = exponentialDecayBase ^ i - 1)</code>
where <code>i</code> is the retry number (i.e., follows <code>seq_len(retries)</code>)

exponentialDecayBase

Logical indicating whether to <code>try</code> silently.

silent

This is useful for functions that are "flaky", such as <code>curl</code>, which may fail for unknown
reasons that do not persist.

Collection of high-level, robust, machine- and OS-independent tools
for making deeply reproducible and reusable content in R.
The three workhorse functions are Cache, prepInputs, and Require;
these allow for nested caching, robust to environments, and objects with
environments (like functions), and data retrieval and processing, and
package handling in continuous workflow environments. In all cases,
efforts are made to make the first and subsequent calls of functions have
the same result, but vastly faster at subsequent times by way of checksums
and digesting. Several features are still under active development, including
cloud storage of cached objects, allowing for sharing between users.

retry: A wrapper around `try` that retries on failure
