Fill And Highlight Countries On A Map

R

The folks at Sharp Sight Labs show how to create a professional-looking filled map in R, including highlighting specific countries:

Let’s point out a few things.

Second, we are simultaneously using the highlighting technique to highlight the OPEC countries.

Finally, notice that we’re using the title to “tell a story” about the highlighted data.

All told, there is a lot going on in this example.

It’s a very interesting example of building higher-quality visuals in R.  I also give them kudos for picking five colors which work for people with every kind of Color Vision Deficiency.  H/T R-Bloggers

Using Cohen’s D for Experiments

Nina Zumel takes us through Cohen’s D, a useful tool for determining effect sizes in experiments: Cohen’s d is a measure of effect size for the difference of two means that takes the variance of the population into account. It’s defined asd = | μ1 – μ2 | / σpooledwhere σpooled is the pooled standard deviation over both cohorts. […]

Comparing Iterator Performance in R

Ulrik Stervbo has a performance comparison for for, apply, and map functions in R: It is usually said, that for– and while-loops should be avoided in R. I was curious about just how the different alternatives compare in terms of speed. The first loop is perhaps the worst I can think of – the return vector is […]
