R

Hi, in this post we are going to explore non-equi-joins using the data.table package in R. non-equi-joins can be utilized, when you want to join two tables based on inequalities. We will use the flights data set, which we will download from github using the fread function. From this data set I am going to generate a second table which will be used as a look up table. More on this later.

Hi, since I uploaded a brand new course on https://www.udemy.com, I would like to give you a brief overview on what you will learn in this course. For now it is available in german only, but the english version is under very active development. The course is called: Regression Pipeline in R and teaches you how to build a Pipeline using tidymodels with workflowsets. If you already know a little bit about Machine Learning and R this course is just right for you.

Dieser Kurs dient als Einstieg in die Programmierung und Datenanalyse mit R & RStudio. In dem Kurs lernt Ihr im ersten Schritt Grundlagen der R-Programmierung. Abschluss des ersten Kapitels bildet ein kleines Projekt, in dem wir die Fläche eines Kreises approximieren. Dafür schreiben wir angepasste Funktionen. Danach erfolgt, eine Einführung in die, aus Sicht des Autors, wichtigsten Pakete für die Datenanalyse. Ihr lernt das “tidyverse” und “data.table” kennen, die in der Praxis sehr häufig für die Datenanalyse benutzt werden.

Hi, if you are interested in analyzing and synthesizing tide curves, you should check out the new version of TideCurves. Version 0.0.5 is now on CRAN https://cran.r-project.org/web/packages/TideCurves/index.html Main changes are: Introducing two new exported functions: BuildTC() & SynTC(). Please see examples and README. Added a new internal function BuildDesign(). The package is on also available on github: https://github.com/moritzmn/TideCurves Best, Moritz

The first real post and already a shameless plug for my R course on https://www.udemy.com … As I just uploaded the course I thought, you might be interested in taking this course, where I talk about the basics of R for beginners. Unfortunately the course is in german for now, but I am going to add english subtitles as soon as I figured out how to correctly use Amazon Transcribe with R to generate german subtitles with a timestamp, which I can then translate into english.

Amazon Transcribe & R Hi, in this post, I will show you some ideas on how to generate subtitles with a time stamp using R and Amazon Transcribe. At first you need at least one mp3 file, or like in my case, 139 files. If you want to use this code, you need to set up an aws (Amazon Web Services) account, which might cost you money, depending on how much you use the services.
