Code Used

#pdf(file="F:/Website/boxplot/points-box-large.pdf", width = 15, height = 7.5)
### Import Data  
  data <- bolus
  split.column <- "DOSE"
  min.required <- 3
    
  data <- data[data["DOSE"] == 120000 & data["TIME"] < 72,]

  data.select <- data[ data$MDV == 0 & data$AMT == 0, ] 
    ### Rows where MDV == 0 and AMT == 0  (Good Rows for plotting x,y)
    
  data.to.plot <- list()
  
  data.to.plot$x <- data.select[,"TIME"]  #x
  data.to.plot$y <- data.select[,"DV"]  #y
  data.to.plot$ids <- data.select[,"ID"]  #ids
  
  data.to.plot$criteria <- data.select[,split.column]

  x.min.lim <- 0
  x.max.lim <- 72
  y.min.lim <- 0
  y.max.lim <- max(data.to.plot[["y"]])
  data.to.plot$x.lim <- c(x.min.lim,x.max.lim)
  data.to.plot$y.lim <- c(y.min.lim,y.max.lim)

  bw <- FALSE

  library(lattice)
### End Import


### Panel Function

  function.of.panel <- function(
    x,
    y,
    groups = groups,
    data.to.plot.in.panel = data.to.plot,
	min.required.in.panel = min.required,
    black.and.white.in.panel = bw,
    subscripts
  ){
  cat("\n\n\nPacket", packet.number(),"\n")
  
  ### Grid
    plot.grid(
      x.divisions = 10,
      y.divisions = 10,
      grid.color = "grey95",
      x.limits = data.to.plot.in.panel[["x.lim"]],
      y.limits = data.to.plot.in.panel[["y.lim"]]
    )

  ### Box'n'Whisker
    plot.box.and.whiskers(
      points.x = x,
      points.y = y,
      minimum.required = min.required.in.panel,
      black.and.white = black.and.white.in.panel
    )

  ### Plot Points
    plot.points(
      points.x = x,
      points.y = y,
      points.symbol = ".",
      points.size = 1,
      points.color = "black"
    )
      

  }
      
### End Panel



### Make Box Plot
  lat.box <- xyplot(
    y ~ x | as.factor(criteria), 
    data = data.to.plot,
    type = NULL,
    aspect=.5,
      # X is twice as long as Y
    groups = ids,
    xlab = "Time [units]",
    ylab = "Response [units]",
    xlim = c(x.min.lim - 0.03*(x.max.lim-x.min.lim)*0.5,x.max.lim + 0.03*(x.max.lim-x.min.lim)*0.5), 
      #0.5 is to compensate for the aspect ratio (aspect)
    ylim = c(y.min.lim - 0.03*(y.max.lim-y.min.lim), y.max.lim + 0.03*(y.max.lim-y.min.lim)),
    main = c("Bolus Data Set\nTime < 72 hr"),
    panel = function.of.panel,
	
    key = list(
      title = "Legend",
      text = list(
        c("Box and Whisker Outliers","Points"),
        col="black"
      ),
      points = list(
        col = c("black"),
        pch = c("o","."),
        cex = c(1)*0.75
      ),
      space = "right",
      cex.title = 1,
      cex = 0.75
    )

  )

### Change Color of Trellis Device and Plot Data
  trellis.device(color = !bw,new = FALSE,retain = FALSE)

### Plot Data
  print(lat.box)

#dev.off()
