In luzlogr: Lightweight Logging for R Scripts

luzlogr

Lightweight logging for R scripts.

Installing

luzlogr is available from CRAN, and can be installed using install.packages(). To install the latest, developmental version from this GitHub repository:

1. Make sure you have devtools installed from CRAN and loaded.
2. install_github("bpbond/luzlogr")

Either way, you can then do:

library(luzlogr)
help(package = 'luzlogr')

Logging

Three functions - openlog(), printlog(), closelog() - provide logging of script output. They provide features including priority levels for logs and messages; optionally capturing all output (via sink); switching between logs; and logging to a text file or arbitrary connection. For example:

openlog("test.log")
printlog("message")
closelog()

The resulting log file test.log looks something like this:

Thu Sep 17 08:46:59 2015  Opening ./test.log
Thu Sep 17 08:46:59 2015  message
Thu Sep 17 08:46:59 2015  Closing test.log  flags = 0
