In joyent/Rbunyan: Joyent Bunyan style JSON logging for R

Description

Joyent bunyan JSON error logging package

Details

R functions to log errors in structured JSON format to a log file. Also provides a memory buffer for tracing back log messages from a setpoint. This can be used to aggregate warnings and errors from multiple calls. Logging is to a single file only. Bunyan logs provide timestamps, hostnames, and process IDs for logs as well as log levels TRACE, DEBUG, INFO, WARN, ERROR, FATAL. Use examples are found in the mantaRSDK package using RCURL headers and other messages. The JSON formatted messages can used with other logging packages by disabling the memory and file write components.
