is it possible to set an option inside a function ((I want to set na.action = na.fail) and have the previous state restored if there is an error so that the function doesn't change the option behind the user's back? Sorry if this has been answered before, but this subject is hard to Google. -- Charles Geyer Professor, School of Statistics University of Minnesota charlie at stat.umn.edu
