Chapter 1
Introduction “The role of statistics in data analysis”
You will need to be “competent” in R • This means for this course that you will need to understand • Vectors • Matrices • Data frames • Subsetting • Assignment • Creating Functions • Plotting • Base R • Ggplot
Make sure you clone package “Intro2R”
Install my package devtools::install_github(“https://github.com/MATHSTAT SOU/Intro2R.git”, build_vignettes = TRUE,force = TRUE)
Plenty of resources – mostly labs!!
