.rda vs. .RData

Are they the same with .RData being the newer format? Thanks,

Re: .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.

Re: .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

Re: .rda vs. .RData

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

[actually I would have called them .Rob or .Robject, and .Rwk or
.Rworkspace but then I noticed that if you had a .Rob you had to have
a .Ros so as not to favour one or other of the project originators :)]
