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?
