Convention on tacit and verbose in R functions

I've seen arguments silent

and verbose

how there are ways to specify whether R functions should print output. For example, silent

appears in try

, while verbose appears in install.packages

. The defaults can be equivalent, i.e. function(..., silent=T)

~ function(..., verbose=F)

.

On the surface, they seem to generally serve the same function. Is there a standard convention on when to use one over the other? I am interested in writing my own functions and packages.
