• Spreadsheets are a common entry point for many types of analysis and Excel is used widely but
  • can be unwieldy and difficult to deal with large amounts of data
• error prone (e.g. gene symbols turning into dates)
• tedious and time consuming to repeatedly process multiple files
• how can you, or someone else, repeat what you did several months or years down the line?

• We will use data from the gapminder project

• By the end of the course we will be creating plots like this in a few lines of code

• Session 1:- RStudio and R basis
• Session 2:- Reading data into R, data manipulation and plotting
• Session 3:- Further plotting, Summarising, joining tables and open-ended practice
