Hi Cheng, Check out the keep() function in package:gdata.
And to be sure the "removed" objects are really removed from system memory i think you need to run gc().

How to remove all R objects in the RAM except for a few specified ones? rm(list=ls()) removes all R objects in the R work space. Another question is that whether removing all R objects actually releases the RAM? Thanks.
