How do I use functions in one R package masked by another package?

Question

I would like to use recode from the car package. But if I have Hmisc loaded, it masks the car version.

There is probably a way to call the masked function. Perhaps there is also a way to force one package to be the dominant one?

you can use something like this `car::recode` and `Hmisc::recode`. — MYaseen208, Feb 18 '12 at 01:35

You could run into deeper problems, but at the top level car::recode should do the trick. Not sure what happens if recode uses functions that are also masked.

That is something package maintainers need to be aware of. Shouldn't be a problem if everything is properly imported and namespaces are used. – Sacha Epskamp Feb 18 '12 at 11:23
i believe namespaces are always used now (R>=2.14) – baptiste Feb 18 '12 at 21:38

Use the namespace (package name): car::recode.
