For pkg zoo:

If you look at the NAMESPACE for zoo you will see that those are indeed exported functions. I believe that is the way to export the behavior for items like for example names(x) <- x, where it assigns values to the name attribute. But nevertheless this is helpful because the app is not identifying the source code for those functions.

Strange Behavior

This should be fixed now. I have extracted the relevant parsing from the base function.

This is proving to be a little more difficult. In {zoo} we have some exported functions such as coredata<-. However, in the source code these functions are defined as "coredata<-" <- function(){...}, so the parsed item is not in the list but is instead interpreted as a string constant. Including all string constants can lead to some undesirable matching. Plus we are not capturing any actual usage such as coredata(x) <- ....
