Re: [R] How do you save in R?
I disagree with Dieter's last point. Whether you use 'attach' or 'load' should depend on whether you want the objects in the file to remain separate ('attach') or mixed into the global environment ('load').

Technically a good point, but I found it helpful for starters who want to avoid the inferno of what's attached now? not to use it at all. My suggestion is to use with() instead because it has a higher locality. I know, many of the examples use attach.

My suggestion is to use with() instead because it has a higher locality. i've seen code where an assumption is made to the effect that packages attached inside a function call will be automatically detached, e.g.: search() (function() attach(list()))() search() unfortunately, ?attach falls short of explaining this is an incorrect expectation, and it might be a good idea to do so. attach may also be confusing in how it interferes with lexical scoping: p = function() print(c) l = list(c=0) attach(l) p() detach() with(l, p()) i.e., attach may modify the behaviour of functions without changing what's passed to them as arguments. vQ __ R-help@r-project.org mailing list https://stat.ethz.ch/mailman/listinfo/r-help PLEASE do read the posting guide http://www.R-project.org/posting-guide.html and provide commented, minimal, self-contained, reproducible code.

My suggestion is to use with() instead because it has a higher locality. I know, many of the examples use attach. As a beginner, I find this whole issue very hard to grapple with. When to use attach with $ syntax data = or load I have seen many books and manuals say to just avoid using attach at all, but several of these then go on to use attach quite often. But I run into conceptual problems with all these methods, particularly when I am trying to operate on subsets of a data frame, and then sometimes need to use the [ and ] syntax, sometimes subset = within a function, and sometimes create a separate data frame to then use (but here attach can cause tons of problems). Do other beginners share my confusion? Can some expert point a path through this confusion? thanks Peter PS As a beginner, I appreciate the time that several posters are now taking to elucidate things that may seem obvious. Peter L.
