s3store(obj, name = NULL, path = s3path(), safe = FALSE, ...)

s3put(..., safe = TRUE)

`obj`	ANY. An R object to save to S3.
`name`	character. The S3 key to save to. If no key is provided, the expression passed as `obj` will be used.
`path`	character. The S3 prefix, e.g., "s3://yourbucket/some/path/".
`safe`	logical. Whether or not to overwrite existing fails by default or error if they exist.
`...`	additional arguments to `s3mpi:::s3.put`.

If you wish to store non-vanilla R objects, such as those containing external pointers to C structures, see s3normalize.

s3put is equivalent to s3store except that it will fail by default if you try to overwrite an existing key.

s3read

## Not run: 
s3store(c(1,2,3), 'test123')
print(s3read('test123'))
# [1] 1 2 3

s3store(function(x, y) { x + 2 * y }, "myfunc")
stopifnot(s3read("myfunc")(1, 2) == 5) # R can serialize closures!

obj <- 1:5
s3store(obj) # If we do not pass a key the path is inferred from
  # the expression using deparse(substitute(...)).
stopifnot(all.equal(s3read("obj"), 1:5))
