R programming: basics to challenging

Question

[pixie@bioinfo]

Hello, I am interviewing for industry positions (bioinformatics) and one of them involves coding tests in R. I have the basics, but just wanted to brush up and move ahead to more skilled level of coding/ competitive coding in R. I have 2 weeks of summer vacation and don't mind paying for any course which is reasonable. I saw a lot of stuff on the internet and too many things are confusing me. Given the limited time available, I wanted some suggestions from the community. Thanks and Regards

Which field are you working on, what what is your current level? If I asked you to write a decent Rmarkdown document that takes input files and options via a params list, and should output a html report including the code and relevant plots, would you basically know what to do? If not then learn Rmarkdown. It is valuable for code and analysis documentation.

If the positions are more about 'dyed-in-the-wool' bioinformatics, rather than "data science", many of the sorts of questions you'll likely get would be similar to those in Rosalind. If you try to solve a bunch of those problems with R, you will become pretty proficient and more than likely will actually answer at least one of the types of questions they'd give you.
