RCircos.Set.Zoom.Plot.Positions | R Documentation |
Set plot position for zooming-in plot by selecting index of default plot positions. The zoomed plot will be aligned with the original plot position such as gene position or a cytoband. The zoom area was defined as fraction of circle circumference, default is 1/8.
RCircos.Set.Zoom.Plot.Positions(zoom.info=NULL, total.genes=11, area.length=0.25, fixed.width=FALSE, gene.width=NULL)
zoom.info |
A vector with chromosome name, start and end position to be zoomed. |
total.genes |
Non-negative integer from 1 ~ maximum number of genes to be plotted. The maximum number of genes is calculated based on track height and will be adjusted inside the function. |
area.length |
Non-negative numeric, for better layout, it must be smaller than or equal to 1/4 (quarter of the circumstance). |
fixed.width |
Logic, if the plot witdth for each data point is fixed or not. |
gene.width |
Non-negative integer, number of units for gene width. |
Numeric vector for index of RCircos.Base.Position
