In my experience, error messages that include the word "closure" almost always mean that I have tried to do something with a function that isn't supposed to be done with a function (undoubtedly not a technically correct statement, but it works for me).
I think that applies here, since time is a function in the R stats package: > find('time') [1] "package:stats" So, consistent with Berend's suggestion, the expression s_fun(parms, time) is passing the time() function to the expression J[time] and it makes no sense to use a function as an index to a numeric vector. I also believe that is why the error message said, "invalid subscript type". -Don -- Don MacQueen Lawrence Livermore National Laboratory 7000 East Ave., L-627 Livermore, CA 94550 925-423-1062 On 2/24/13 2:24 AM, "Berend Hasselman" <b...@xs4all.nl> wrote: On 24-02-2013, at 10:59, Jannetta Steyn <janne...@henning.org> wrote: > Hi All > > I have Googled the message Error in J[time] : invalid subscript type > 'closure', but can't quite make sense from the results that I get.

The error is staring you in the face. The second argument in the call of s_fun is "time" which is nit evaluated immediately. You probably meant "times".
