问题 On a given line of the RStudio console or script writing area, the cursor as it flashes on the screen is shifted from its true position, where text is inserted. Say I want to delete a character on a given line. I click right in front of it, and the red cursor flashes where it should. But when I press backspace, the character six spots to the left gets deleted instead. This behaviour gets worse as the line goes on, so near the end of a long line, the offset is of 13 characters while it is only

问题 I'm running 64 bit R on Ubuntu 12.10 AMD64. I recently added additional 8GB of memory to my system making it a total of 12GB. But I notice that R gives me an error whenever the memory usage (of a single R session) goes above 4GB. When I ran 6 R sessions in parallel, each consuming ~ 3 GB of memory, my over all memory usage increased up to 11 GB. But a single R session is not able to use more than 4GB! I need to train a random forest model over a large data set and I need > 4GB with a single R
