Thing To Try After useR! part 2 (TTTAR2) Originally, this post was supposed to be a sequel to TTTAR1 about h2o machine learning. Since TTTAR1 I have been carrying out more h2o tests both locally and on the cloud with the very kind support of Nick Elprin from Domino. ... [Read more...]

A few months ago I did a mini project using open crime data and R to create crime visualisations. At that time, I was already thinking about a web app using Shiny but I couldn't justify the time to develop the app and then set up a server etc. Not ... [Read more...]

To cut a long story short, I always wanted to write professional-looking documents (technical reports and potentially my thesis) with R codes. No more copy and paste. No more Microsoft Word. At the same time, I don't feel comfortable with LaTeX. Somehow I found a workaround with knitr, xtable, R ... [Read more...]
