 Setting up PL/R - function calls fail Hi all, I am currently trying to create a development environment including PostgreSQL 8.0.0rc1, R 2.0.1 and PL/R on a system running Fedora Cora 1. So far, I have suceeded in setting up PostgreSQL and R as a shared library - unfortunately I have not been able to link these two spheres by adding the PostgreSQL add-on PL/R due to some mysterious probs. I thoroughly followed the setup instructions for PL/R (see http://www.joeconway.com/plr/doc/plr-install.html) and arrived at being able to register PL/R with PostgreSQL properly and even to create PL/R-specific functions. >But< whenever trying to invoke these functions, I end up with a single exception, even for simple ones which are just supposed to return the previously passed arguments: ######snip####### ERROR: R interpreter parse error ######snip####### A closer look at the postmaster's/ postgres's log-file reveals that a hardly more specific exception is thrown at this level, i.e.: ######snip####### ERROR: R interpreter parse error DETAIL: R parse error caught in "PLR17706 <- function(arg1,arg2) { if (arg1 > arg2) return(arg1) else return(arg2) }". CONTEXT: In PL/R function r_max ######snip####### Even gdb monitoring did not provide any further hint, using older PostgreSQL, R and PL/R versions didn't make a difference. I would kindly ask for your help and thoughts! best regards, Stefan      |
