Buggy attempt at MonetDB-rmath

I am trying to adapt MonetDB-gsl to use the rmath library. My code is at: https://github.com/mclements/MonetDB-rmath Under Ubuntu 16.04 LTS, I used: sudo apt install r-mathlib git clone https://github.com/mclements/MonetDB-rmath cd MonetDB-rmath make sudo make install // start up MonetDB server with a test database mclient -d test -s "select sys.pchisq(20.0,5.0);" This compiles but when I try "select sys.pchisq(20.0,5.0);" I get the error: SELECT: no such binary operator 'pchisq(decimal,decimal)' Any guidance would be appreciated. (You may ask why one would want to do this when one could use embedded R - I wanted to see how fast and easy it was to use the rmath library.) Kindly, Mark.
