Equivalent of Matlab "clearvars -except" in R

Question

I want to remove some of the variables, NOT all as remove() and rm would do.
In Matlab I'd wright:
clearvars -except Environnement Species *_species Latitude Longitude

So you want to delete all variables except for specified ones? — Jan Sila, Dec 15 '16 at 09:13

This is the best I can do. This creates a,b,c and deletes everything the the Global Env except for b.

a<-1
b<-2
c<-1:5
rm(list = ls()[!ls() %in% c("b")])
