If you really love R, you should put it on your iPhone.  Apple gives the measurements for its products here. Let’s use a little `grid` magic with `ggplot2` to make a chart for the back of your iphone similar to this.

``require(grid)require(ggplot2)# thanks for the Apple measurements# https://developer.apple.com/resources/cases/x11(  height = as.numeric(convertX(unit(58.55, "mm"), "in")),  width = as.numeric(convertX(unit(115.15,"mm"), "in")))# seems Rstudio make it hard to select a dev use until the new dev is# Activedev.set(which = dev.next())# draw anything to activate our windowgrid.text("my R iphone case")``

``# draw your most beautiful plot with ggplot2 or lattice a good example# thanks http://sharpstatistics.co.uk/r/ggplot2-guide/p <- ggplot(iris, aes(Sepal.Length, Sepal.Width)) + geom_point()p + facet_grid(. ~ Species) + stat_smooth(method = "lm")``

``# draws rectangular and circular(camera) cutoutgrid.roundrect(  y = unit(28.975, "mm"),  x = unit(57.275, "mm"),  height = unit(57.95, "mm"),  width = unit(114.55, "mm"),  r = unit(8.17, "mm"),  name = "iphoneback")grid.circle(  y = unit(49.78, "mm"),  x = unit(106.45, "mm"),  r = unit(3.46, "mm"))``

Cut and insert in or paste/tape to your case.

A little more seriously, this is a good way to test how your graph might appear on an iOS device if you have the need.  Just use the screen measurements from the Apple specs.
