[R] remove objects(1-20, 25-30) OR remove objects(...) except(...)??

[Agustin Lobo]

I would make a vector with the list of
files to removed. If the position
is the only way you have to select, you could use:

toberemoved <- ls()
toberemoved <- toberemoved[c(1:20,25:30)]

check that toberemoved is what you want to remove and then

remove(list=toberemoved)
