I know it sounds like a silly question but whenever i click on "save to file" it doesn't save. whenever i use the function attach(___) it doesn't work, and says object can not be found. i have a series of data (0,0,0,1,1) that i need to save, then i want to attach(...) it in another R window. Please help. Thanks -- View this message in context: http://www.nabble.com/How-do-you-save-in-R--tp23590795p23590795.html Sent from the R help mailing list archive at Nabble.com.

You should use File/Save Workspace instead, but better avoid this approach and use save(mydata1, mydata2, file="mydata.Rdata") instead to have reproducible results.> whenever i use the function attach(___) it doesn't work,Best avoid using attach at all. It can be more confusing than helpful.> and says object can not be found. i have a series of data (0,0,0,1,1) that i > need to save, then i want to attach(...) it in another R window.Use load("the file you saved above.Rdata") instead in the new R Window.

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.
