Points

Variation

Use

To plot the points on the graph

Arguments

points.x: - All X values of points that will be plotted
points.y: - All Y values of points that will be plotted
points.symbol: - Defaulted to "x". The default when plotting a regular plot is "o".
points.size: - Default is 1
points.color: - Default is "black". May be replaced with rgb() or color system.

Notes

Almost always plotted last, unless under an a-b-line

Code

'plot.points' <-
function( 
  points.x = x, 
  points.y = y, 
  points.symbol = "x", 
  points.size = 1, 
  points.color = "black"
){
cat("\nPlotting Points\n")

  panel.xyplot(
    x = points.x,
    y = points.y,
    pch = points.symbol,
    cex = points.size,
    col = points.color
  )
}
