[R-sig-Geo] R2Winbugs - problem with workign directory

[Virgilio Gomez Rubio]

Hi James,

Try to use the full path (e.g., /home/james/mycode/...) instead of just
".".

Also, from the manual page:

 If 'useWINE=TRUE' is used, all paths (such as 'working.directory'
     and 'model.file', must be given in native (Unix) style, but
     'bugs.directory' can be given in Windows path style (e.g.
     "c:/Program Files/WinBUGS14/") or native (Unix) style (e.g.
     "/path/to/wine/folder/dosdevices/c:/Program Files/WinBUGS14").
     This is done to achieve greatest portability with default argument
     value for 'bugs.directory'.


Hope this helps.

Virgilio
