![]() In the video, the speaker explains how to use the setdiff function. 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. 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. 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. Thus, when one uses RStudio, they are still. Cross-platform functionality like such makes RStudio way ahead of its. RStudio is actually an add-on to R: it takes the R software and adds to it a very user-friendly graphical interface. ![]() R Notebooks do not have their own file format, they all use. There are a few minor differences in where things are located in the menus (Ill point them out as we go along) and in the shortcut keys, because RStudio is. The beauty is that there are packages now by which you can write Python/SQL in R. The diff Function is by far not the only R function that computes differences of data objects. Technically, R Markdown is a file, whereas R Notebook is a way to work with R Markdown files. 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. Diff (x, lag = 2 ) # Apply diff with lag # 5 -1 -7
