B1001 Laboratory 6 - Biological Data for Computers 2 This week s lab is the first of two new labs on data visualization and quantitative training. Quantitative training refers to computational biology, data science, electronic data archiving, data cleaning and manipulation, statistics, mathematical modelling, effective data visualization (including maps and phylogenies), and interpretation of graphs and figures. Do not let these terms scare you. They only sound scary and you will only be covering the material at the most introductory level. In this lab we simply want to introduce you to the basics of using R and RStudio. R is a software environment for statistical computing and graphics. RStudio is a graphical interface software package which works in conjunction with R. Both will run on a Windows, Mac or Unix machine, but not on a tablet. (You may use RStudio Cloud as an alternative to downloading the software). Follow this link BIOL 1001 - Quantitative skills to begin this week s lab. As you read through this webpage you will be directed, through a number of hyperlinks to the Quantitative skills for biology guide (https://ahurford.github.io/quant-guide-all-courses/ ). As you follow the links you will work through Chapters 1 , 2 , 3 and 4 in the Quantitative skills for biology guide. Follow all instructions and links. Make sure to complete the TRY IT! , EXERCISE and HAND IN activities. (Many of these have been included in this week s assignment.) We also want you to cover Chapter 9 Making graphs in R in the Quantitative skills for biology guide in addition to the chapters mentioned above. LABORATORY 6 BIOLOGICAL DATA I
