Hello everybody,

is there a possibility to install and use multiple versions of a R library 
at the same time? 
A few words regarding the background of this question:
If I change functions of an already developed package, I have to 
verify complex functions in a lot of R applications. So it would be useful
to use different versions of a function/library and switch to the newer 
function/library application by application to avoid crashes. I know that 
the library function has an argument "version", but finally I don't know 
how to install and use different versions at the same time.
Any ideas and hints are appreciated - thank you in advance!

	Kind regards,
