I particularly found AllAboutUX.org useful for selecting the UX evaluation methodology to utilise, and eventually resorted to using Intrinsic Motivation Inventory.

R Graphical Representation – Installing tikzDevice Package

I have R code embedded within LaTeX files that make use of R plots, and I use Sweave to generate corresponding standalone TeX files. In addition to that though, I also make use of the R tikzDevice package to ensure that the fonts in my R plots are consistent with my LaTeX document. As it turns out, R commands are output at a low level as tikZ commands [1]. Continue reading “R Graphical Representation – Installing tikzDevice Package”
