I recently suggested to someone ( http://stackoverflow.com/questions/6789055/r-inconsistency-why-add-t-sometimes-works-and-sometimes-not-in-the-plot-functi/6789098#6789098 ) that the should use methods("plot") or methods(class="function") to locate the documentation on the plot method for objects of class "function", but they pointed out that these don't actually work. I can't figure out why not: src/library/graphics/man/curve.Rd contains the line \method{plot}{function}(x, y = 0, to = 1, from = y, xlim = NULL, ylab = NULL, \dots) and src/library/graphics/DESCRIPTION contains S3method(plot, "function") [presumably the extra quotes are in there because function is a reserved word?] I'm not sure where else the information should be. Searching around in the code tree for information on tail.function (which is listed in the methods: > methods(class="function") [1] as.list.function head.function* print.function tail.function* I find the same S3method syntax, so I guess the quotation marks aren't the problem ... Any ideas?
