  condition = "Complete",
  shape.cal = 19,
  shape.cv = 19,
  width = 1,
  size = 2,
  col.cal = "blue",
  col.cv = "red",
  xaxis.title = "Component",
  yaxis.title = expression(R^2),
  title = paste("Plot of R2 for the", condition, "model"),
  legend.name = NULL,
  x.legend = 0.9,
  y.legend = 0.2
)
