Thanks. I had seen this but it didn't register. I made this change to all the potential conflicts (the packages ellipse and mgcv are never in an @import statement), but I still get the conflict messages. John Karon

Therefore you can write ellipse::ellipse without requiring importFrom(ellipse,ellipse) in your NAMESPACE.

Here is the entire set of import commands from NAMESPACE. Also, when I use the function ellipse, I code it as ellipse::ellipse; similarly for using in.out.

Something in your NAMESPACE file (derived from some comment in your code by roxygen2) is importing ellipse::pairs, even though you say you don't want to do that.
