Sorry for > posting without checking first. Understandable mistake. Confusingly similar file extensions are confusingly similar. I'd have called them .Rob for the current .rds file format (single object), and .Ros for the current .rda file format (>1 objects).

My bad, I was thinking of rds (?saveRDS). RData and rda are mentioned under ?data as alternate file extensions for the same data format.

Re: [R] .rda vs. .RData
Hi Jeff. Can you point me toward the documentation for "rda saves content of one variable, with no associated name"? I don't seem to find it in ?save ?load etc. Thanks, Ista On Mon, Apr 23, 2012 at 5:58 PM, Jeff Newmiller wrote: > No, RData saves both the variable name and corresponding content of multiple > variables. rda saves content of one variable, with no associated name.

Re: [R] .rda vs. .RData
No, RData saves both the variable name and corresponding content of multiple variables. rda saves content of one variable, with no associated name. The latter allows for greater flexibility in importing the data later into different working environments, the former is convenient for recreating a particular working environment. --- Jeff NewmillerThe . .
