R: do not write log file for VennDiagram

Question

I use R (version 3.1.2) and the VennDiagram package (version 1.6.16).

Since the last update, the VennDiagram package creates a log file with the name VennDiagramDATE_TIME.log (with DATE and TIME - the date and time it was created) in the current working directory.

How can I suppress this log file? Or delete it as soon as the diagram is completed? I did not find anything in this guide ...

Answer 1

As Ed Hagen already mentioned, VennDiagram uses the use of the futile.logger package. You can suppress registration messages below the ERROR severity level by setting a threshold to the appropriate registrar. In your case:

 futile.logger::flog.threshold(futile.logger::ERROR, name = "VennDiagramLogger") venn.diagram(...) 

gotta do the trick.

For more information on using futile.logger, see http://www.r-bloggers.com/better-logging-in-r-aka-futile-logger-1-3-0-released/ .

Answer 2

VennDiagram uses the futile.logger package. To suppress logging, try:

 flog.threshold(ERROR)
