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.

I suppose/hope, thats not the problem year 2003 month 11 day 21 language R >
