The second way is to use the list discussion. Due to the fact that it is a character vector, it can be corresponded to an externally defined vector providing it higher adaptability. This enables various variables to be deleted when making use of a loop or any type of case wright here the exact same section of code is resupplied.# clear all in r tutorial through list argument> a = 5> b = c(1, 2, 3)> d = c(x=5, y=4, z=10, t=2)>> a<1> 5> b<1> 1 2 3> dx y z t5 4 10 2>> rm(list = c("a", "b"))>> aError: object 'a' not found> bError: object 'b' not found> dx y z t5 4 10 2In both situations, each variable targeted for removal produces an item not uncovered error once dubbed the second time reflecting that it has actually indeed been rerelocated.
