A colleague and I played with this a couple years ago, and found success: https://github.com/applied-science/rdata I expect Clojisr provides its own mechanism but I'm not familiar with it.

clojisr should work well with most datatypes stored in rdata/rds (it's read on R side and then transfered to Clojure as robject)

One note about rdata, since it relies on Renjin it doesn't support newest rdata format (afair)
