Dear all,

I would appreciate a suggestion on the following : I am using the tracks() function "ggbio" in order to represent multiple tracks : eg tracks("track1" = track1, "track2" = track2, ..., "trackn" = trackn , etc) ;

however the presence of track1 or track2, ... trackn,  in the final output depends on some upstream variables :  sometimes, I could include only track1, or track1-and-track2, etc ....

which is the simplest way to display only the tracks that have received 'approval' by a variable, 

thank you,

bogdan

consider do.call(tracks, x)

where x is a list whose contents are determined programmatically

Thanks, Vincent !
