Hi there, Thanks for your time in advance. I am using an add-on package from Cran. After I updated this package, some of my programs don't work any more. I was wondering if there is anything like version control so that I could use the older version of that package; or if I could manually install the previous version and how I could acheive it? I am not a regular R user; although it is supposed to be very easy, after spending many hours on this, I still haven't figured out how to proceed. Your help will be greatly appreciated. Thanks. Le

You need to download one of those and install it: but watch out for other packages that depend on the newer one. In the long run, it's probably a better investment of your time to fix your programs to work with the new package. (Or possibly report to the package maintainer if they have introduced a bug.) Prior to R 2.9.0, it was possible to install multiple different versions of packages, but this never worked perfectly, and it has been dropped. Duncan Murdoch
