Hi, my "history" in Mac for R does not work. I found the solution is GNU readline and re-installation from source. is there any other way to solve this? i really do not want to re-install: which means I need to install many packages, blabla... i used to use JGR (which solved that problem) but found sooo many bugs with it... -- Weiwei Shi, Ph.D Research Scientist GeneGO, Inc.
