Add a new track or go to an existed track

spiral_track(ylim = c(0, 1), height = 0.8, background = TRUE,
    background_gp = gpar(col = "#EEEEEE", fill = "#EEEEEE"), reverse_y = FALSE,
    track_index = current_track_index() + 1)

Arguments

ylim: Data range of the y-locations.
height: Height of the track. The value can be the fraction of the distance of the two neighbour loops. The value can also be a unit object.
background: Whether to draw the background of the track, i.e. border and filled color of background.
background_gp: Graphics parameters of the background.
reverse_y: Whether reverse the direction of y-axis.
track_index: Index of the track.

Details

If the track is already existed, the function simply mark the track as the current track and does nothing else.

Value

No value is returned.

Examples

spiral_initialize()
spiral_track(height = 0.8)


spiral_initialize()
spiral_track(height = 0.4, background_gp = gpar(fill = "red"))
spiral_track(height = 0.2, background_gp = gpar(fill = "green"))
spiral_track(height = 0.1, background_gp = gpar(fill = "blue"))
