Hi,

I'm trying to visualize results using Gviz package.

Is it possible to add a straight horizontal line to a track created using DataTrack object?

I'm looking for something like abline(h=n)  in base R.

thanks,

Silvia

From the DataTrack man page, in the Display Parameters section:

'baseline=NULL': Numeric scalar. Y-axis position of an optional

          baseline. This parameter has a special meaning for

          mountain-type and polygon-type plots, see the 'Details'

          section in 'DataTrack' for more information.
