732A94 Advanced Programming in R
Course information
Autumn 2017
This is the coursepage for the course in Advanced R programming.
The first course occation will be in room P18 on Tuesday 2017-08-29 13:15-15 Lecture and 15-17 a computer lab!
Course Content
The course introduces general programming techniques and their practical implementation in the R language. More specifically, the course includes:
- reading data from file, from the internet, and printing to output,
- data structures, functions and objects,
- iteration and conditional statements,
- numerical linear algebra in R,
- debugging,
- object-oriented programming,
- performance enhancement,
- parallel programming,
- literate programming,
- development of R packages.
Course structure
The course contains 7 lectures, 2 computer labs and 5 seminars.
The two first weeks will focus on basic R programming and syntax and students will work individually.
The last five weeks will focus more on advanced concepts and students will then work in groups of two and two.
The best thing is that the students work with their own computer. See below how to install R, git and R-Studio.
The course contains three teaching activities:
- Lecture (FÖ) Introduction of new concepts.
- Computer lab (DATALAB) Individual computer lab with individual help.
- Seminar (SE) Each student group will present their current work and we will discuss eventual problems.
The following content will be presented each week:
| Lecture | Material |
|---|---|
| 1 | Data structures, subsetting and intro to functions |
| 2 | Program control, functions and R packages |
| 3 | Performant code: Writing R packages, roxygen, testthat, git/github |
| 4 | Linear algebra, vignettes & rmarkdown, graphics and object-orientation in R |
| 5 | Advanced Input/Output (I/O) |
| 6 | Performant code: Writing fast code, parallelism and handling big data |
| 7 | Intro to Machine learning, big data and data wrangling |

Software
The students are suggested to work using their own computers. For this course the following software is needed. Everything is open source and free.
Information on how to install R and R-Studio: - Windows, - Mac - Linux/Ubuntu
Assignments
The course contains 7 assignments that all are mandatory.
Assignment 1 and 2 will be turned in as an R script file. All assignments needs to be fully correct to get a pass. To test your assignment the R package markmyassignment can be used.
Assignment 3 to 7 will be fully implemented R packages that should be possible to install directly from github.com. To turn in the package just send in the github adress to the package. Read the particular instructions in each lab for what is needed to pass.
All labs and seminar assignments have a deadline. But please observe, on occation, you will present your assignment on a seminar before the deadline has passed! This means that sometimes, you will not be completely finished with the assignment on the seminar, but that is ok.
