Under Windows, R imposes limits on the total memory allocation available to a single session as the OS provides no way to do so: see memory.size and memory.limit. Please include sessionInfo() when you're posting to the list; it makes clear what software and hardware you're using. This did not make sense since I have 2GB of RAM. navigate here If the above cannot help, get a 64-bit machine with as much RAM as you can afford, and install 64-bit R.

My understanding of it is that R keeps some memory in reserve that is not returned to the OS but that can be accessed by R for future objects. Basically, if you purge an object in R, that unused RAM will remain in R’s ‘possession,’ but will be returned to the OS (or used by another R object) when needed.
