(1) getwd() is irrelevant if you load() a fully qualified filename
(2) if the file is actually in the working dir, load("ari18.test2.rda") should do
(3) there is no guarantee that an rda file contains an object of a name related to the file name 
(4) To see what is inside a .rda, try e <- new.env(); load("my.rda", e); ls(e)
