[Bioc-devel] warning in R CMD check

[Joern Toedling]

Hi Alex,

use the function's argument 'quietly' to suppress the warning.

require(anotPack, character.only=TRUE, quietly=TRUE)

btw, I would suggest to spell out TRUE in functions, since some users
might unwisely have used 'T' as a variable name.

Regards,
Joern
