MazamaCoreUtils

A suite of utility functions providing functionality commonly
needed for production level projects such as logging, error handling,
cache management and date parsing.

Background

The MazamaCoreUtils package was created by MazamaScience to regularize our work building R packages and R-based web services.

The main goal of this package is to create an internally standardized set of functions that we can use in various systems that are being run operationally. Areas of functionality supported by this package include:

  • python style logging

  • simple error messaging

  • cache management

  • date parsing

  • source code linting

Installation

Install from CRAN with:

install.packages('MazamaCoreUtils')

Install the latest version from GitHub with:

devtools::install_github('mazamascience/MazamaCoreUtils')

This project is supported by Mazama Science.
