Adding tcltk to Depends may not always be the desried solution. If
tcltk is already in Suggests, for example, and the intention is to
optionally provide GUI features, then the code may be correct as-is.
That is, codetools will issue the NOTEs if you have a function that
looks like:
f <- function() {
if (require("tckltk")) {
someTckltkFunctionHere()
} else
otherwiseFunction()
}
}
There are a number of packages in the BioC repository that provide
such optional features (not just for tcltk) and it would be nice to
have a way of declaring the use such that the NOTE is silenced.
[Note 1: I don't have any ideas at the moment for how this could
work.]
[Note 2: Despite the false-positives, I've already caught a handful of
bugs by reading over these NOTEs and think they provide a lot of value
to the check process]
