What do you think of adding an argument mustExist=FALSE or mustFind=FALSE to system.file() such that if it is TRUE and no file is found then system.file throws an error? Then my example could be scan(what="", sep="\n", system.file("DESCRIPTION", mustExist=TRUE)) and it would throw an informative error message inst...
