Hello,
I encounter the problem that one library I use masks the function

another library I use so that the gam in the other library cant

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>
Thank you and kind regards,
gigi
