When I try to do dbConnect(), I get an error "LOGICAL() can only be applied to a 'logical', not a 'integer'", and it happens inside the call to rociConInit. The driver from dbDriver looks fine, and I call dbConnect with arguments dbDriver("Oracle"), and correct username, password and dbname. (I can use these parameters fine in SQLDeveloper.) The arguments that are being sent to rociConInit inside dbConnect look fine.
I'm on Windows 10, with ROracle_1.3-1 DBI_0.7, R version 3.4.2, platform x86_64-w64-mingw32/x64, Running under Windows >= 8 x64 (build 9200).
