How do I suppress the environment line when printing an R function?

Question

How can I suppress the environment/namespace line when I print a function from a package? I've tried reassigning the function to the global environment. I have tried entering into the foobar environment. I've tried gimmicks and games, even with R to make this work. It seems like there should be a simple way to do it.

> x2
function(x) {
    return(x * x)
}
<environment: namespace:foobar>

Well, if you want to change how functions are printed, create your own print.function. I think this should work for you

print.function <- function(x,...) {
    environment(x)<-globalenv(); 
    base::print.function(x,...)
}

For example

x2<-function(x) {
    return(x * x)
}
environment(x2)<-asNamespace("stats")

base::print.function(x2)
# function(x) {
#     return(x * x)
# }
# <environment: namespace:stats>

x2
# function(x) {
#     return(x * x)
# }
