...notice that as.list.environment has a sorted=FALSE argument already, so I guess identical(names(x), names(as.list(x))) could be made to be TRUE, assuming the order is at least persistent, if undefined, so that is a nice property.

...the behavior is the same. Maybe a different name would be less "loaded" and imply lack of order, something like keySet(). But do we really need this?

...ile, but it was something like if (defined(x{'c'})) { print x{'c'}; } # This is still two lookups, but it has the "defined" concept. or maybe even if (defined( foo = x{'c'} ) ) { print foo; } Thanks again for the timings!

I also just noticed that there is a bug: identical(ans, FALSE) should be is.null(ans). So no error is thrown: > methods:::genericForPrimitive("foo") NULL Will fix.

...s=TRUE))) is now for an environment 'x'. One could think to change the default of 'all.names' in as.list.environment(.) from FALSE to TRUE, but that may break code in subtle places and I don't think we should go there.

All, So that suggests that .GlobalEnv[["X"]] is more efficient than get("X", pos=1L). What about .GlobalEnv[["X"]] <- value, compared to assign("X", value)?

Hi I think the following behavior is a regression from R 3.2.5: > match(iconv( c("\u00f8", "A"), from = "UTF8", to = "latin1" ), "\u00f8") [1] 1 NA > match(iconv( c("\u00f8"), from = "UTF8", to = "latin1" ), "\u00f8") [1] NA > match(iconv( c("\u00f8"), from = "UTF8",

How about unique them both and compare the lengths? It's less work, especially allocation. Pete ____________________ Peter M.

...erim. Similarly, the "assign" function does nothing with the "immediate" argument. I'd be interested to hear if there is any support for a "fetch"-like function (and/or deprecating some unused arguments). All the best, Pete Pete ____________________ Peter M.
