• The cheatsheet gives you a good overview.
• R Studio provides also a useful reference guide.
• Look at the R Markdown Webside from R Studio for a first start.
• To dig deeper you will find many youtube videos and online tutorials.
  • A good one is, for instance: R for fledglings

Start your first R Markdown file that should render a html document and save it under any name. In lecture 8 on visualizations you were asked to answer the following questions using the hydro dataset (file "data/1111473b.csv"):

1. What happens if you make a scatterplot of station (x) vs temp (y)? Why is the plot not useful? What would be a better plot?
2. What happens if you make a boxplot of cruise (x) vs psal (y)? Why is this plot less suitable? What could be an alternative?

If you have done this exercise you can simply use your code and copy and paste it into the code chunks of your .Rmd file. If you haven't done the exercise you have now the opportunity to make up leeway.

1. Start with R code chunks for loading the data and required libraries
2. Add code chunks for i) any data modifications ii) any plot
3. Think about which code chunks should be evaluated (eval=TRUE) or not displayed (echo=FALSE)
4. Think about the dimensions of the figure and add the required specifications in the chunk options
5. Include different headers and subheaders
6. Add your answers and think about whether you want to use i) any ordered or unordered lists ii) text in bold or italic
7. Add a webside link that fits to the topic
8. Add an image
