[R] package MonteCarlo error: object 'packages' not found

R-users,

I can't tell what's causing the following error. The vignette does not 
make a reference to a "packages" option or parameter.

Loading required package: abind
Loading required package: codetools

 > infest_kud_fun<-function(x,A,B){
+?? equation1=exp(A-(B*x))
+?? return(list("equation1"=equation1))
+ }

This looks like the sort of thing that you should ask the package
maintainer (?maintainer).
