R: don't write log file for VennDiagram

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

Since my last update the VennDiagram package creates a log file called VennDiagramDATE_TIME.log (with DATE and TIME being date and time at creation) in the current working directory.

How can suppress this log file? Or delete it as soon as the diagram is done? I haven't found anything about this in the manual...

Solution

  • Like Ed Hagen already mentioned, VennDiagram is making usage of the futile.logger package. You can suppress logging messages below ERROR severity, by setting the threshold to the corresponding logger. In your case:

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

    should do the trick.
