Programming in R

Image saved from my new ShinyApp
Over the past few days I've been playing around with R, a statistical language which is essentially an offshoot of S, which was created in the 1980's. R has some powerful features which enable to it rapidly create meaningful graphical illustrations. I've really enjoyed manipulating some of the datasets on Kaggle with it. Here's a ShinyApp I published to demonstrate a simple R program to track where different plant and animal species live within the US national parks.

How NOT To Write Code / How To Decipher Bad Code

Confusing code is bad code. In this post I'll be talking about one of the worst coding practices: using nondescript variables. As an example, we'll be looking at a simple problem from Project Euler (#28). I'll give you an example using really bad code and then we'll look at how we can decipher it and make it more clear and understandable. First, here's the problem: Starting with the number 1 and moving to the right in a clockwise direction a 5 by 5 spiral is formed as follows: 21  22 23 24  25 20   7   8   9  10 19  6   1   2 11 18   5   4   3  12 17  16 15 14  13 It can be verified that the sum of the numbers on the diagonals is 101. What is the sum of the numbers on the diagonals in a 1001 by 1001 spiral formed in the same way? Ok, so now check out this solution:             int i = 1; int j = 1; int s = 0; ...

Merging Files into a Single .NET Assembly

.NET assemblies can be single-file or multifile.   As I've been preparing to take Microsoft Exam 70-483, I came across the Al.exe command, a tool which is installed along with Visual Studio. Al stands for "Assembly Linker" and when you run it, it "links" different manifest or resource files together into a single assembly. If you work with .NET at all, you probably have a pretty good idea of what an assembly is, but here's a simple definition from Stack Overflow : "A chunk of (precompiled) code that can be executed by the .NET runtime environment. A .NET program consists of one or more assemblies." -Adrian Grigore Here's a more technical definition from Wikipedia :  "A compiled code library used for deployment, versioning, and security."  Normally when you create a new project in Visual Studio, VS pretty much creates the assembly for you. You don't have to worry about merging different files together using the c...
