RStudio is an Integrated Development Environment (IDE) that facilitates R programming in making import of data and the search for help much easier.  Moreover RStudio highlights variable properties in one window (such as how many elements  it has, and their sizes) and colour-coding of code make the R code itself more transparent and readable. We wondered whether we should go for the default IDE for R, but after a few years teaching R programming to students it was clear that they all found RStudio helpful in  the learning process.
