It depends on the change, but I never install an unreleased package into 
the main library, so do not need sudo for 3).  I have a 'test-library' 
library that is in R_LIBS in ~/.Rprofile and I use solely for package 

If this is a change to the NAMESPACE or an unexported object you do need 
to re-install, but many changes can be tested via source()ing the new file 
and example().

If the test suite is good enough, 'R CMD check' may do all the tests you 
need without installing the test package anywhere else.
