The environment of your function, as written, is the global
environment which means that free variables in it are looked up there
but you want it so that those free variables are looked up in the nlme
namespace first so set its environment as shown:
library(nlme)
nlme <- asNamespace("nlme")
unlock
Thanks for your help. I am making great progress, but there are still some
things that are puzzling me.
In the code below, I add a cat() statement to `coef<-.corExp`. Sure enough,
when I run lme(), it prints. (awesome!) However, the function does not seem
to be able to find the C script "spatial_f
You did change it. Try nlme:::corExp
Also note that asNamespace("nlme") is a nicer way to refer to it.

Sorry, I am still not understanding this. I tried using the unlock binding
function, but the function remains unchanged after I attempt an assignment:

[1] TRUE
> unlockBinding("corExp",environment(corExp))
> bindingIsLocked("corExp",e
See ?lockBinding

I tried editing the corExp function (added a line) within the nlme
environment with the following code, but it looks like my declaration did
not have any effect. I am guessing it is locked some how. Is there an easy
way to do this or am I treading into complicated waters? (I just picked up R
a year
Thanks.
How do I make my function visible to others? Will assignInNamespace do that?

Hi,
I am trying to place my own functions in the nlme environment:
The following statement works:
environment(coef.corSPT) <- environment(getS3method("coef","corSpatial"))
but this one returns an error:
environment(get("coef<-.corSPT")) <-
environment(getS3method("coef<-","corSpatial"))
Error
