R help - Apr 2010 - when setting environment: target of assignment expands to non-language object

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 in environment(get("coef<-.corSPT")) <-
environment(getS3method("coef<-",  :
  target of assignment expands to non-language object

What should I do?

Thanks.

Mike

I'm not that does what you want.  It doesn't place your function in the 
environment, it attaches the environment to your function.  The 
difference is that other functions won't see yours, but your function 
will see whatever is in that environment.

If you want to change the coef<-.corSPT object, use backquotes to treat 
it as a name:
environment(`coef<-.corSPT`) <-  ...
