Introduction to Data Management, Statistical Analysis and Graphics With R

INTRODUCTION

This course will help participants learn how to program in R and how to use R for effective data analysis. Participants will also learn how to install and configure software necessary for a statistical programming environment and describe generic programming language concepts as they are implemented in a high-level statistical language. The course covers practical issues in statistical computing which includes programming in R, reading data into R, accessing R packages, writing R functions, debugging, profiling R code, and organizing and commenting R code.

LEARNING OUTCOMES

Upon successful completion of the course, participants should be able to:

  • Use R to perform descriptive statistics including graphics
  • Perform basic inferential statistical analyses including regression analysis
  • Read and write data files
  • Perform data manipulations (eg, creating new variables, merging data sets)
  • Write and use R script files
  • Use R packages
  • Write and use R functions
  • Perform programming in R including loops.
