In the end it appears that there was no problem in accessing the gdata package or any of its components and that the poster's problem stemmed from issuing this series of commands: library(AER) data() at which point the poster saw the names of AER data files listed and assumed that the data() command showed the data set names of the last loaded library. Based on this assumption when he issued this series of commands: library(gdata) data() and saw AER listed again he thought that gdata had not been loaded. In fact the data() command lists the names of the data sets of *all* installed packages, and not just the last loaded one, so if AER is the alphabetically first package that is installed it will always appear first. Thus to view gdata's data set names in this list one would have to scroll down to view the names off the screen. Things which confused the issue further were that the poster was using a virtual machine to run R, which might have caused problems in determining where the library was located but in fact did not, and one responder somehow assumed that the question related to read.xls (a function in gdata) and its perl dependency but as indicated the problem actually had nothing specifically to do with gdata at all much less read.xls or perl.
