How do I remove all objects except one in R?
rm(list=ls()) #will remove ALL objects
But he wanted to remove all objects ***except one***!!! So what's the

I can't see any way except a rather round-about kludge to do what the

rm(list=ls()[!grepl('^QQQ$',ls())])
cur
package gdata has function keep() which does just what the OP asks for.
