Supressing R output

Question

I need to supress output from an R function -- I have found a hack, but it feels like the wrong way to do it.

Right now, i'm combining invisible and capture.output -- which is effective, but it feels very hacky to chain together two similar tools to supress the output.

The function's output I need to supress is blpConnect from the Rbbg package.

require(Rbbg)
invisible(capture.output(conn <- blpConnect()))

For those that are interested, invisible returns the following:

> conn <- invisible(blpConnect())
R version 3.0.1 (2013-05-16) 
rJava Version 0.9-4 
Rbbg Version 0.4-155 
Java environment initialized successfully.
Looking for most recent blpapi3.jar file...
Adding C:\blp\API\APIv3\JavaAPI\v3.4.8.1\lib\blpapi3.jar to Java classpath
Bloomberg API Version 3.4.8.1 

Same output for invisible(conn <- blpConnect())

What's the appropriate way to do this?

Enlightening commentary on the appropriate use of the two commands, and when and why they work as they do would be valuable.

Answer 1

conn <- blpConnect(verbose=FALSE)
