Hello Cafe, I am pleased to announce the first release of Rlang-QQ. You can find it at http://hackage.haskell.org/package/Rlang-QQ-0.0.0.0. The package provides a quasiquoter which makes it easier to call R (http://www.r-project.org/) using values calculated with GHC. Variables in quasiquoter prefixed with hs_ lead to the corresponding haskell variable being made available to R (provided there is an instance to marshal values of that type). In other words, `hs_foo' in the quasiquote will start off as whatever `foo' is on the haskell side. For now no attempt is made to translate anything on the R side back to haskell. Regards, Adam Vogt
