This course is scheduled in period 4.
The aim of this course is to provide an introduction to R, a computer language and environment for statistics and graphics. The course will focus on getting familiar with the R environment by means of RStudio, to use R for manipulation and exploration of data and to perform all statistical analyses learned in the basic and advanced statistic courses, i.e. simple linear and multiple linear regression models, analysis of variance for CRD, RCBD and factorial designs, ANCOVA, non-parametric methods and analysis of categorical data. Basic programming as well as visualization of results in R will also be part of this course.
After successful completion of this course students are expected to be able to:
- read data into R from various sources;
- carry out statistical analyses as learned in previous statistical courses, with the help of the R language and environment for statistical computing and when necessary extend its basic functionality with specific packages;
- adapt and combine standard functions from basic R and packages to solve a given problem;
- adequately use standard programming constructs: loops, if-then-else statements, repetition, selection, functions, etc., to write basic program scripts to fully automate the statistical analyses;
- visualize results from statistical analyses, when possible, with the basic R graphics system;
- write reports in Rmarkdown language in which the statistical analyses and results visualization are integrated (as being part of Reproducible Research).
Computer practicals (attendance compulsory) analysing practical data with R and R- Studio.
Text examination: weekly assignments and an end-assignment.
