I find that the R layout() function is a lot easier and more flexible to work with when combing multiple plots into one graph. I have in the past also played around with the par() function, but layout() is my favourite 🙂 Continue reading “R Graphical Representation – Multiple Plots in One Graph”
I conducted a user experience (UX) study, as part of an evaluation process for a paper submission to ICADL 2012 –the paper was accepted–, towards the end of July 2012. I particularly found AllAboutUX.org useful for selecting the UX evaluation methodology to utilise, and eventually resorted to using Intrinsic Motivation Inventory.

I work with a lot of XML documents and was until recently using XML Copy Editor, both as my XML editor and for executing XPath expressions. I recently started working on a project that, in part, involves converting metadata stored in a legacy MS Access database to XML documents. I wanted an easier way of verifying the XML metadata files and naturally had to make do with XPath. Continue reading “XPath Expressions Using XMLlint Navigating Shell”
LaTeX/Sweave integration is awesome! Dynamic reporting made easy indeed. Integrating the overall workflow with tikZ functionality right within R is even better as it esures that your plots have a consistent look and feel through out your report.
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 . Continue reading “R Graphical Representation – Installing tikzDevice Package”
