Since installing R 2.14.0 on my Mac (a Mac Pro running 10.6.8) an issue has arisen when using the vi editor in conjunction with the edit() command. More specifically, commented lines disappear from edited functions when using [functionname.R] <- edit().

That is, if you have created a function called “test.func” as such:

function ()
{
# This is a test
ex _ 4
    duh <- seq(1, 10)
    fuh <- seq(11, 20)
    plot(duh, fuh)
}

you will of course get an error message:

Error in edit(name, file, title, editor) :
  unexpected input occurred on line 4
 use a command like
 x <- edit()
 to recover

When using the “x <- edit” (or in this case, test.func <- edit()), the comment “This is a test” will disappear from the edited function.

Does anyone have any insight into this problem?

Thanks,
Jeff Freedman
