I have RMySQL installed on my OSX implementation of R, but get the following errors when trying to use it: Error in dyn.load(x, as.logical(local), as.logical(now)) : unable to load shared library "/usr/local/lib/R/library/RMySQL/libs/RMySQL.so": dlcompat: dyld: /usr/local/lib/R/bin/R.bin Undefined symbols: _getopt_long _load_defaults _mysql_affected_rows _mysql_close _mysql_errno _mysql_error _mysql_fetch_fields _mysql_fetch_lengths _mysql_fetch_row _mysql_field_count _mysql_free_result _mysql_g Error in library(RMySQL) : .First.lib failed I'm hoping there is a RMySQL guru out there somewhere that can help me out. TIA, cjf
