If save() fails because an object is not found,
it should not overwrite an existing file.
> a <- 1:9
> save(a, file = "a.rda")
> rm(a)
> load("a.rda")
> a
[1] 1 2 3 4 5 6 7 8 9
> rm(a)
> save(a, file = "a.rda")
Error in save(a, file = "a.rda") : object 'a' not found
> load("a.rda")
Error in load("a.rda") : error reading from connection
I've been saving copies of huge objects into
files like a.rda, then removing the objects.
If I then happen to save again, I don't want to lose
my data.
