Wel, just let the user give the function in form of an argument, say
"foo", and use your code so that
bar <- function(x, ....., foo){
if(missing(foo)) foo <- Namespace::my.func
.....
}
but perhaps I misunderstood your question.

Hi,
I have defined a function (my.func) which is used as parameter (f) of another
function. As I want to give the user the possibility to define his own function
instead of my.func, how can I find out if in other functions, the parameter f
has the my.func value (if the user has defined a new function or not)?
Moreover, I think I should impose to the user to use another function name than
my.func for this (?). Or a boolean variable is better to be used to indicate if
my function (my.func) or user-defined function is used?
Thanks
Carol
