Last year, I presented an informal course on the basics of R Graphics University of Turku. In this blog post, I am providing some of the slides and the full code from that practical, which shows how to build different plot types using the basic (i.e. pre-installed) graphics in R

These notes are an introduction to using the statistical software package R for an introductory statistics course. They are meant to accompany an introductory statistics book such as Kitchens “Exploring Statistics”. The goals are not to show all the features of R, or to replace a standard textbook, but rather to be used with a textbook to illustrate the features of R that can be learned in a one-semester, introductory statistics course.

READ ME FIRST:  This collection provides additional resources to support classes teaching from The Analysis of Biological Data by Michael Whitlock and Dolph Schluter, broken down by chapter.  Each chapter post has at least three buttons:  Datasets, which links to the datasets for that chapter; R Code, which links to the R code for that chapter; and R Pubs, which links to a different version of the R code page that contains additional code output and results.

A few years back, a famous psychologist published a series of studies that found people could predict the future — not all the time, but more often than if they were guessing by chance alone.

The paper left psychologists with two options.

"Either we have to conclude that ESP is true," says Brian Nosek, a psychologist at the University of Virginia, "or we have to change our beliefs about the right ways to do science."

Nosek is going with Option B — and not just for psychology experiments. He thinks there's something wrong with the way we're doing science. And he launched a massive project to try to fix it.
