RColorBrewer is an R packages that uses the work from http://colorbrewer2.org/ to help you choose sensible colour schemes for figures in R. For example if you are making a boxplot with eight boxes, what colours would you use, or if you are drawing...
To be reductive, visual displays of quantitative information might be reasonably categorized on a continuum between “data display” and “statistical graphics.” By statistical graphics, I mean a plot that displays some summary of or relationship amongst several variables, likely having undergone some processing or analysis. This may be as simple as a scatterplot of a … Read more
This file illustrates the computer code to use spatial filtering in the context of Bayesian Model Averaging (BMA). For more details and in case you use the code please cite Crespo Cuaresma and Feldkircher (2010). In addition, this tutorial exists as ...
We've continued to get useful feedback and ideas from our posts on the combination dotplot/boxplot and other ways to craft similar displays. Another notion is the violin plot, which combines a boxplot and a (doubled) kernel density plot. While the ba...
The online training provider Statistics.com has three great courses based on R coming up in the next few months: Nov. 5 - Dec. 3: "Graphics in R," with Paul Murrell Nov. 20 – Dec. 18: Support Vector Machines in R" with Dr. Lutz Hamel Dec. 17 - Jan. 22: "Geostatistics in R" with Prof. David Unwin The courses take...
Previosly, I calculated a bunch of ad-hoc power curves from GISTEMP data. Power is essentially a reframing of the p-value, to see the significance of the trend lines in the global temps. However, power calculations are inherently very noisy, hence, my ad-hoc way of aggregating the data. Another method is to bootstrap through the responses 
Kudos to several of our readers, who suggested simpler ways to craft the graphical display (combination dotplot/boxplot) from our most recent example.Yihui Xie combines a boxplot with a coarsened version of the PCS scores (using the round() function) u...
In honor of World Statistics Day and the read paper that my co-authors Chris Wild, Maxine Pfannkuch, Matt Regan, and I are presenting at the Royal Statistical Society today, we present the R code to generate a combination dotplot/boxplot that is useful...
We recently had a dilemma for an OSI publication about the design for the graphs. There will be dozens of these graphs showing the mean score on a given variable for nearly 11000 parents from 10 countries. This example is for household wealt...
As I am working on my dissertation and piecing together a mess of notes, code and output, I am wondering to myself “how long is this thing supposed to be?” I am definitely not into this to win the prize for longest dissertation. I just want to say my piece, make my point and move on. I’ve heard that...
