Digitalisierung von Forschungsprozessen

Quelle: Gedankensplitter Autor: Peter Baumgartner

Nach meinen drei vorigen Beiträgen zu RWordPress nun ein weiteres Beispiel, wie Digitalisierung Forschungsprozesse transformieren kann. Der Beitrag zeigt wie sich in derProgrammiersprache R – mit der Hilfe einiger Erweiterungen – nicht nur Daten (statistisch) verarbeiten lassen, sondern Kommentare als auch die Interpretation in einem Arbeitsprozess publiziert werden kann. Die damit verbundene Strategie heißt Literate Programming und bedeutet, dass Dokumentation als auch der Quelltext des Programms in einer gemeinsamen Datei zugänglich sind. Weiterlesen

Learning how to use the RWordPress package

Quelle: Gedankensplitter Autor: Peter Baumgartner

This is the follow-up article from the previous post Publishing R Statistics directly into WordPress. This time I will explain in more detail how to apply the different packages. There is a companion webpage where you can see the content of the different program chunks. You will see how to post text, graphic, uploading files, setting categories and tags, fill in the excerpt and providing a thumbnail.

In contrast to the previous post I have now establised the facility to upload graphics resulted from R calculation automatically to the imgur.com website. This is very important because otherwise the transfer to WordPress would encrypt the pictures to an awful peace of code. An example how this looks can be seen from my first trial. Weiterlesen

In contrast to the previous post I have now establised the facility to upload graphs resulted from `R` calculation automatically to the imgur.com website. This is very important because otherwise the transfer to `WordPress` would encrypt the pictures to an awful peace of code. An example how this looks can be seen from my first trial. Weiterlesen

Publishing R Statistics directly in WordPress

Quelle: Gedankensplitter Autor: Peter Baumgartner

This post is an experiment: Writing a program in R and publishing directly the results into WordPress. This experiment is part of my ongoing effort of the last few months to collect material for a new book. I want to describe new working procedures in scientific research which are — thanks to progress in digitalization like open source tools, open data — now feasible. My focus on these new work flows are guided on the one hand by the goal to improve reproducibility of all research phases and on the other hand to facilitate research procedures in closing the digital gaps between different research tasks.

Efficient R Programming – Book recommendation

Quelle: Gedankensplitter Autor: Peter Baumgartner

The book „Efficient R Programming: A Practical Guide to Smarter Programming“ by Colin Gillespie & Robing Lovelace is a collection of very important resources. It is not only helpful for the advanced data scientist but also the intermediate and even R beginner can benefit a great deal from the book. It covers important R related everyday subjects and activities. Each self-contained chapter starts with 5 top five tips and discusses practical issues. The book is rich in internet references, which I have collected and presented in 10 link lists, divided by the book chapters. Weiterlesen

R – most minimal learning resources

Quelle: Gedankensplitter Autor: Peter Baumgartner

With December last year, I started to learn data science using R. As a self-determined learner, I had not only to find resources, that are adequate to my learning goals and status of competencies but also to plan and organize my spare time for my self-organized continuing education.This article reports about my strange learning behavior and closes with 3 tips on R learning resources for the beginner, suggesting the most minimal learning set for the prospective data scientist.

Hands-On Programming with R – Book recommendation

Quelle: Gedankensplitter Autor: Peter Baumgartner

„Hands-On Programming with R“ by Garrett Grolemund is a very gentle introduction to programming with R. It starts with explaining the installation and the R user interface and covers step by step more advances topics. It is is not a programming book per se, as you will learn how to use R for data science. If you want to learn R from scratch and you are a newcomer to programming, then this is the book I would like warmly to recommend! Weiterlesen

Yesterday I have experimented with R packages for generating Twitter Word clouds. In this post, I will give some hints how to proceed. I will also refer to my GitHub repository, where you can find the complete program code. I have added some examples in generating all the twitter clouds for all member of the IBM staff with a Twitter account, for the department and the university account. Weiterlesen
