When I upgrade in Windows from say 2.6.2 tp 2.7.0 I do the following 1. Install 2.7.0 in a new directory
2 Rename the library subdirectory in the new version from library to library2 3 Copy the library subdirectory in 2.6.2 to 2.7.0 4 Copy the contents of library2 to the transferred library. This re-installs the updated base packages. 5 Within R run update.packages(checkBuilt = TRUE) and you will be presented with a list of packages and be given the option of updating each package. This procedure is easy to implement. I have used it for several updates and it has always worked well Best Regards John. 2008/5/8 Duncan Murdoch <[EMAIL PROTECTED]>: > On 5/8/2008 10:40 AM, ravi wrote: >> >> Hi, >> Ouch!
