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!
R CMD INSTALL --help
tells us to use the option
--with-package-versions
allow for multiple versions of the same package
when installing the packages.
