R help - Feb 2013 - Error in J[time] : invalid subscript type 'closure'

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.
What
does it mean?

I'm trying to access an element in an array. Here is a short bit of code
that produces the error:

s_fun <- function(parms,time) {

  with(as.list(c(parms)),{
    print(J[time])
  })
}
times = seq(from=0, to=100, by = 0.1);
v<-14
J<-c(rep(c(rep(0,10),rep(v,10)),5))
parms=c(J)
out <- s_fun(parms, time)

Thanks for your help

Regards
Jannetta

Look at your code carefully. 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".
