Hi Nancy, in contrast with some other statistical packages (such as SPSS) R puts all the data in active memory. In theory this should make R faster than SPSS, because SPSS reads the data-file of the harddisk when analysing it (this counts for large files). Disadvantage of this behavior is, that file-sizes are limited in R.
Most operating systems can 'add' virtual memory to your computer using the harddrive (this is called the swap-file), in which data is stored that isn't used immediately. CAn you tell us more about your computer, for making it possible to give a more detailed sollution to your problem? For instance, what operating system do you use, what kind/size of datafile and what analysis are you trying to run?
