Lattice Graphics Package

Lattice is one of the CRAN project’s recommended packages, and among the earliest packages to be developed. It is also a graphics package which allows users to produce sophisticated displays of data with very simple commands. Come along to hear a little of Lattice’s origins, take a tour of its capabilities and learn how to use some its more advanced functions.

Speaker: Robert de Graaf

Robert de Graaf is an engineer who became interested in Statistics when he underwent Six Sigma training while working for a manufacturing business in Melbourne’s west, and went on to complete a Master of Scientific Studies in Statistics. More recently he has left manufacturing to join RightShip as a Risk Modeler.

    Answers to some questions posed last night:

    Question 1: Can you include numeric scale on Lattice trivariate functions (and how)?

    Answer – Yes, you use the the scale argument, which must be included as a list.

    Hence, given you have your surface dataframe pre-prepared:

    wireframe(z~x*y,, scales=list(z=list(arrows=FALSE, distance =1)))

    (distance positions the z-axis text label. You can also include a rot argument - e.g. rot=90, to choose text label orientation)

    Question 2: Can you use the print() function to arrange graphics objects produced from multiple R graphics packages?

    So far as I can tell, the answer is a qualified ‘yes’, where the qualification is that you need to be working with a graphics package which produces a storeable graphics object – lattice obviously does, and it looks like ggplot2 does also. Another package I selected at random, vcd appears not to, however.

    Looking forward to it. I feel like I'm sesiously under-using Lattice.
