Learn how to upload Markdown files to Medium including local images, formulas, cross-references, and bibliography — a scientific, concise workflow.
I love writing Markdown at work and for my private projects and my website as well. However, when publishing Markdown files to Medium by copy & paste from my WYSIWYG Markdown editor most of the formatting got lost. That was always a lot of work to refurbish the article again within the Medium web interface. Lots of wasted time! Here comes the solution; if you are a Markdown fan like me. Or you might get a Markdown fan.
7 reasons to use Markdown for your documentation. Markdown is the least common denominator. It just focuses on text — without any clutter.
Software engineering has a lot to do with writing code. And it is even more about writing text which humans — such as customers, project managers, team members — need to read and understand such as
Microsoft Word, Apple Pages, OpenOffice, LibreOffice, and others are all word processing software focusing mainly on layout which is useful in many cases — especially for print. …
Editor’s note: Anxiety can be serious medical condition, while the author has written about anxiety here in relation to code, if you are experiencing real anxiety, please seek medical help. The following article is obviously not medical advice.
Why you should delete a lot of source code without fear — as early as possible in your project!
Source code deletion anxiety is a disease in software developers leading to a lot of problems in the future as it produces unnecessary software clutter for you and others which must work with your codebase. Unfortunately, it cannot be cured by a physician…
Whenever I need to process dates and times in R (and other programming languages) I usually run into difficulties — parsing, printing, time zones, daylight savings, time differences. Probably you are one of those poor wretches like me. So this article is for those and my future self which always forgets about those concepts. This article is a loose connection of hints, packages, and functions showing how to cope with dates and times.
A standard representation of a point in time (that is a date together with time) in R uses the so-called UNIX Epoch time or POSIX time which…
You will ask: “Why unit tests? My code is working!”. Unit testing helps to create robust code. After a short motivation what robust code is, I give a survey of the basic unit testing idea. Finally, I show how to use them quickly in R, even for simple scripts (no burden to create R packages).
Unit tests are important for writing robust code — they allow to…
A common problem in R occurs when attaching several libraries at the top of your script by library() calls. Loading all symbols into the global R environment often results in name conflicts. The last imported package wins the fight — the order matters, by which libraries appear at the top of your script!
R is a fast-growing language with a vivid community contributing countless packages (c.f. R Package Documentation). Chances are that yesterdays script will not work tomorrow because an updated package now exports a function conflicting with another globally attached package.
So I propose here the mindful use of…
