Hello, I am an employee at The George Washington University, and we have recently had trouble getting R to launch without error directly after installing. There are no errors displayed during the install, but when the program is run, a warning is displayed for ever package that is referenced in defaultPackages which says the package cannot be found. I have checked the .libPaths() value, and it is pointing to the correct location (C:\...\R-2.2.0\library). In addition, I have attempted to re-install the software with the same result consistently. I have attempted searching online for this problem, and all posts online point to the .libPaths() value being incorrect, but I have checked this value and reset it a number of times, but the problem continues to persist. Is there any known solution to this problem or another pool of answers I should look at? Thanks.
