R: don't write log file for VennDiagram

Question

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...

yes, but then I have to find out the name of the log file first. Which I could do but I was hoping there is something easier to suppress the writing of the logfile in the first place. — Jonas, Oct 28 '15 at 14:48
The source code is not huge - - just go in there and comment out the lines which write the file. — Carl Witthoft, Oct 28 '15 at 15:29

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.

For more infomation about the usage of futile.logger see http://www.r-bloggers.com/better-logging-in-r-aka-futile-logger-1-3-0-released/.

The default really should be no log file – stevec Apr 27 '20 at 15:28
I agree with stevec. Doing this as default for what is essentially a *plotting library* is truly dreadful. The package author needs to _flog_ (!) this particular hobby horse more appropriately and preferably elsewhere. Meanwhile there's the venn package, as one alternative. – Big Old Dave Jan 18 '21 at 12:44

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

flog.threshold(ERROR)
