Listing 1 is the R command used to produce the ux-evaluation.tex TEXfile that
is used within the main L TEXdocument; Listing 2 shows the Sweave code that
A
was used to generated the barplot in Figure 1; and Listing 3 shows the portion
of the LaTeX document that uses the Sweave output file as input.
