You will need an account at github.com for parts of the Git lesson. Basic GitHub accounts are free. We encourage you to create a GitHub account if you don't have one already

NOTE: We did create a public repo on github for the workshop. But please note that it is possible to create a private repo so you can develop without fear of your work being visible before you are ready for it to be publicised

*install.packages('knitr', dependencies = TRUE)

Just as a note, there was an error that occurred when trying to query the gapminder matrix to obtain all rows where the life expectancy column was greater than 80. The solution for this is to move the conditional statement to before the comma, like below:

*gapminder[gapminder$lifeExp > 80,]
