You absolutely must install packages properly (with R CMD INSTALL) on R 2.0.1. What you did has never to my knowledge been documented, and often did not work under 1.9.1, so you were fortunate.
You will find it easier to find the pertinent information if you search for the concept `package' (you are talking about a package) under `package' not `library'. See
3.1 Can I install packages into libraries in this version?
Yes, but you will need a lot of tools to do so, unless the author or the maintainers of the `bin/windows/contrib' section on CRAN have been kind enough to provide a pre-compiled version for Windows as a `.zip' file. ...

I have a library for R 1.9.1, it is very easy to setup a library in R 1.9.1. For example: I want to setup a library "test" for R1.9.1. 1. Create a folder "test" in the direct X:\ R\ rw1091\ library \. 2. Create a file "DESCRIPTION" in the direct X:\ R\ rw1091\ library\ test\. 3. Modify the "Package:" and "Title:" item to "test" in the file "DESCRIPTION" . 4.Create a folder "R" in the direct X:\ R\ rw1091\ library\ test\ . 5.Create a file "test" in the direct X:\ R\ rw1091\ library\ test\ R\ . 6. Add all the function into the "test" file. Then I can call the "test" using command " library (test) ". I setup the library using the same way in R2.0.1, but the library can't work. The error message is " Error in library(test) : 'test' is not a valid package -- installed < 2.0.0? " I search the help file and document but still can't upgrade the library. Who can tell me how to upgrade library from R 1.9.1 to R 2.0.1 or give me a sample, thanks.
