[R] grid lines when plotting its object

[M. Sutter]

Dear R community
When plotting an its object (with 'plot(..)), grid lines are 
automatically added which I cannot control with parameter 'tck/tcl'.
Furthermore the vertical grid lines (time axis) do not comply with the 
automatically generated tickmark locations.

Can somebody tell me how to handle these grid lines ?
How can I switch off the grid lines ?
Thanks a lot for any advice and I'd like to thank all the R 
developpers/experts for spending their precious time answering questions 
on the r-help mailing list and making it very valuable for R users like me.
