When I run some large optimizations in R under Windows it puts a heavy load on the CPU, which makes other applications that run at the same time very slow. Is it possible to instruct R to be less aggressive in its use of computer resources, so I can use my computer for other purposes while running R (probably considerably slower) in the background?
