You can expect to update RStudio much more often. In the video, the speaker explains how to use the setdiff function. The Preview version includes new (upcoming) features, but it is also generally very stable and highly usable. R Notebooks do not have their own file format, they all use. Useful descriptive statistics include the group means, standard deviations, sample sizes, and the mean difference, which is the difference between the two group. If you want to learn more about the computation of differences in R, you could also have a look at the following video tutorial of the YouTube channel Xperimental Learning. Technically, R Markdown is a file, whereas R Notebook is a way to work with R Markdown files. Note: Base R is always required to run R-Studio. If you're having a problem running code and think it might be IDE-related, it's a good idea do try it out in. (On of my favourite figures from Modern Dive, below, illustrates the difference nicely). To give you some examples: I can recommend to have a look at functions such as difftime for the calculation of time differences setdiff for the identification of elements of a data object A that are not existent in a data object B or sweep which applies an operation such as minus to a data matrix by row or by column. R is a simple basic tool where you can write you program and run the code but R-Studio is an advance version of R with Integrated development environment which provides better graphics and few more options which generally useful in development work. If you're using RStudio, you're using R RStudio is just an IDE (Integrated Development Environment) in which you are using the R language. R1 is the software that performs the actual instructions. It makes a lot of sense to explore other difference-functions as well, to be able to decide from situation to situation which functions suits your need the most. R and RStudio are two distinctly different applications that serve different purposes. The diff Function is by far not the only R function that computes differences of data objects. In the following figure, you can see how this output is computed:įigure 1: Calculations of diff Function with Lag of Two.Īlternative R Functions for the Calculation of Differences In this example, we are using a lag of 2. The RStudio console features tab-code-completion and live help for function coding. Diff (x, lag = 2 ) # Apply diff with lag # 5 -1 -7 Output of commands will typically be displayed in the console.
