What simpleCache is

simpleCache is an R package that stores and reuses R objects to help make analysis pipelines reusable, restartable, and reproducible. It suits both interactive work and automated processes that reuse objects across scripts or R sessions. To create a cache, choose its location and name, then provide the R code that produces the object. When called, simpleCache loads the named cache if it exists; otherwise, it creates it. The package can recreate and reload caches, list or delete them, and configure a default cache directory. Cached objects can be assigned to environments, including the global environment. For cluster-based workflows, simpleCache interfaces with batchtools to build caches on cluster resource managers. It is self-hosted, with Windows and macOS binaries and a source package available through CRAN. The package is free and distributed under the 2-Clause BSD License. Its documentation advises choosing names for cached objects that are not expected to change. Questions, feature requests, and bug reports are handled through the GitHub issue queue.

Who it suits

simpleCache suits R users who want to reuse computed objects in interactive analysis or automated pipelines across scripts and sessions. It also fits cluster workflows that use batchtools and users who want control over where caches are stored.

Limits

The documentation advises using cache names for objects that are not planned to change.

Getting started

1. Visit https://code.databio.org/simpleCache/.
2. Choose a Windows or macOS CRAN binary, or download the source package.
3. Choose a cache location and provide a name for the object.
4. Supply the R code that produces the object and call simpleCache.

Verdict

Choose simpleCache if you work in R and want to reuse objects across analysis scripts, sessions, or pipeline runs. Its batchtools interface also supports cluster resource manager workflows. Look elsewhere if you need a hosted service rather than a self-hosted package.
