Hi Fraser, "textplot" is fairly similar to the "thigmophobe.labels" function in plotrix. I think the problem is that when the user passes an explicit position for the labels with the default "new=TRUE" argument, the "pos" argument is passed to the "plot" function, causing the warning. If the "pos" argument was named rather than extracted from "...", this could be avoided. However, if you want to specify the position of the labels, you could probably use the "text" function.
