How to suppress warning messages when loading a library?

Question

I\'m trying to run a r script from the command line, but I get warning messages when packages are loaded:

C:\\Temp>Rscript myscript.r param
Warning messag         


        

Answer 1

These are not messages but warnings. You can do:

suppressWarnings(library(RODBC))

or

suppressWarnings(suppressMessages(library(RODBC)))

to suppress both types.

Answer 2

I put this at the top of all my scripts and preface my library loads with it:

shhh <- suppressPackageStartupMessages # It's a library, so shhh!

Then you can load the library thusly:

shhh(library(tidyverse))

and rely on perfect silence.
