Simple R package for UN Comtrade API

I have recently been doing a lot of work in R, a statistical programming language, and have started accumulating a small collection of functions that I regularly use. One of the tools I have particularly come to rely on is this function to obtain data from the United Nation’s Comtrade database, a great source for country-to-country trade statistics. Since there seemed to be no R package that provides access to their new API (which is still in beta), I simply wrote a function for myself based on the sample code on their homepage and kept it with my personal files. Motivated by posts like this, however, I decided to put the code into an R package and share it here for others to use. [...]

Finding local extrema in Matlab and Octave via fminbnd()

I recently had to work on a Matlab assignment that required the use of fminbnd() to find local extrema. As I typically work on Octave rather than Matlab I ran into some problems getting my code to work within both programmes. As it turned out, Matlab and Octave handle the function slightly differently, so I thought I’d share my findings to save others some headache. First of all, some background information: fminbnd() is a Matlab/Octave function to find a local minimum of a continuous function within a specified interval … [...]

LyX CJK set-up based on XeTeX and xeCJK

I have recently been playing around with LyX and XeTeX, a Unicode extension for TeX, to find a set-up that allows me to switch easily between various East Asian languages without entering LaTeX code. With the help of a few friends, the xeCJK manual and Richard Heck over at the LyX Mailing List, I was able to define LyX Text Styles for Chinese (Simplified and Traditional text), Japanese and Korean that can be selected via the context menu right from within LyX itself, allowing me to focus on the content of my writing and leaving the worrying about Unihan issues to someone else … [...]
