R help - Sep 2014 - modify function in a package

Dear R users,?
There is a package called NanoStringNorm with a function called NanoStringNorm.
What I want to do is to change the NanoStringNorm function from the package with
my own copy that is written in my.nanostringnorm.R.?
But if I do the following:?

source('my.nanostringnorm.R")
unlockBinding("NanoStringNorm",
as.environment("package:NanoStringNorm")) ;?
assign("NanoStringNorm", NanoStringNorm,
"package:NanoStringNorm") ;?

Although, it now correctly called my NanoStringNorm, it doesn't recognize a
function called inside my NanoStringNorm that called another functions in the
NanoStringNorm package.?
So, I have to change all such functionswith NanoStringNorm:::function.name.?
How should I replace the NanoStringNorm function but still able to call other
function in the package??
I still have package NanoStringNorm in my search path but somehow it can't
find the other function.?

TIA,?
Lin

Take a look at assignInNamespace. It's also possible to set teh environment
of a function:

?assignInNamespace
?`environment<-`
