Hello,

I'm wondering whether there is a "quiet" mode for AnnotationHub, in which it would only print serious warnings or errors. Currently it displays snapshot and cache information whenever accessed. An example follows.

I'm interested in such a "quiet" mode because I regularly access AnnotationHub objects over and over within a pipeline, and so my logging information becomes clogged with these messages.

Thank you,

Rob

If you were to put your AnnotationHub calls inside an invisible that would hide the messages. For example,

invisible(AnnotationHub())

Thank you for the quick response. invisible doesn't seem to accomplish what I want, but suppressMessages does. Thanks for the simple fix suggestion.

Best,

Rob
