Dear All:
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.
Best Regards
