Cause of R package not loading quietly?

Sometimes when you load a new package in R there is a message printed. There are built-in arguments in functions library and require to prevent this form happening, namely "verbose" and "quietly." (see here).

However, I cannot get the package 'plyr' to load without a message. I have tried setting quitely = TRUE and verbose = FALSE (and the combination of the two) but I still get this following result:

library(plyr,quietly = T,verbose = F)
Warning message:
package ‘plyr’ was built under R version 2.15.3

I've also tried using suppressMessages(), but still got the same result.

Any ideas of how to suppress this warning message?

Solution

  • Looks like a warning to me. Wrap the call in supressWarnings to prevent the warning from being printed. Or reinstall the package to get rid of the warning entirely.
