NEW FEATURES
o serialize(connection = NULL) now returns a raw vector (and not
a character string). unserialize() accepts both old and new
formats (and has since 2.3.0).
serialize.Rd:
The function \code{serialize} writes \code{object} to the specified
connection. Sharing of reference objects is preserved within the
object but not across separate calls to serialize. If
\code{connection} is \code{NULL} then \code{object} is serialized to a
raw vector, which is returned as the result of \code{serialize}.
^^^^^^^^^^
\section{Warning}{
These functions are still experimental. Names, interfaces and
values might change in future versions (and was changed for \R 2.4.0).
\code{.saveRDS} and \code{.readRDS} are intended for internal use.
}
\examples{
x <- serialize(list(1,2,3), NULL)
unserialize(x)
## test pre-2.3.0 interface as a length-one character vector
y <- rawToChar(x)
unserialize(y)
}
all seem clear enough to me ..., including the statement about being
experimental.
