Dear gigi;

There is a special syntax for detaching packages and since you have  
not shown what you did, it is not possible to determine what is  
happening (or not).

?detach
# Perhaps:
detach(package:unwanted)

If you want to use a function, say "weighted.mean",  in a package, say  
"Hmisc" that has been masked by another package, then use the "::"  
operator to pull it out of its namespace:

Hmisc::weighted.mean(arguments)   # I don't know if this is a real  
function

Further (real) example after loading Hmisc.

 > units
function (x, ...)
UseMethod("units")
<environment: namespace:Hmisc>
 > base::units
function (x)
UseMethod("units")
<environment: namespace:base>
