[Rd] Suppress specific warnings

[Brian Lee Yung Rowe]

For my logging package (futile.logger) any log statements coming from a package are assigned to a package namespace. This way you have control of log messages at a package level (e.g. I can set the default log threshold to DEBUG, while package 'A' has a log threshold of WARN). 

I seems a hierarchical namespace facility would work for the below case as well.
