In MichielNoback/bintestr: The BioINformatics automated TESTing environment for R

This R Markdown document contains exercises to accompany the course "Data analysis and visualization using R".
This document contains the exercises themselves plus (in most cases) a R code chunk to complete, correct or create. There are some code chucks here bounded with this line: ###### TEST CODE - DO NOT REMOVE OR EDIT #######. These code chunks are used to give you feedback on the correctness of your implementations. Do not edit or remove these chunks (unless you hate feedback). For more details on using R Markdown see http://rmarkdown.rstudio.com.

When you click the Knit button a document will be generated that includes both content as well as the output of any embedded R code chunks within the document. You can embed an R code chunk like this:

summary(cars)

You can also embed plots, for example:

plot(cars)

Note that the echo = FALSE parameter was added to the code chunk to prevent printing of the R code that generated the plot.

Before Knitting this document, check if you have the devtools package installed, by typing library(devtools) in the console. If this fails, you need to install it by typing install.packages("devtools").
