I have the following code that uses R.Net on Windows:

engine = REngine.GetInstance(); engine.Initialize(); engine.Evaluate("library(tseries)");

Unfortunately it outputs some messages to the console which I want to suppress.

I tried using the NullCharacterDevice in Initialize and the invisible R function but unfortunately they did not suppress the output of the evaluate call.

engine = REngine.GetInstance(); engine.Initialize(null, new NullCharacterDevice()); engine.Evaluate("invisible(library(tseries))");

How can I suppress all console output of R.Net?

    engine.Evaluate("suppressWarnings(library(tseries, quietly = TRUE, warn.conflicts = TRUE))") you could also wrap it arround suppressMessages function if there are messages that you dont want
