Save and serialize
Also, if it it adds any value to what you are looking for, the output of serialize() also has header information, cf. R-devel thread 'Small inconsistency in serialize() between R versions and implications on digest()' started March 7, 2007: http://www.mail-archive.com/r-devel at r-project.org/msg07931.html It caused us some headaches when trying to generate identical output of the same input using different versions of R. It was solved in that thread. See code for digest::digest() on how to skip/ignore that header. /Henrik

Hi all, Is there any relationship between save and serialize? ?Do they use the same algorithm?
See the R-internals manual: there is more info in the R-devel version, not least because saveRDS() is added to the mix. But basically serialize() and saveRDS() use the same format, and save() writes a header and then serializes a pairlist of the objects given. 'The same algorithm' is somewhat misleading here: strictly no, as they manage to use four entry points to the code base.
