I named the function my.sum rather than just sum because R allows you overwrite built-in functions. The demo program begins by defining a simple R function that returns the sum of two numeric values in order to illustrate basic syntax: Then enter the command source("functions.R") to execute the program. Enter the command setwd("C:\\ProgramDefinedFunctionsWithR") to point the working directory to the location of your script.

To run the program, copy and paste the code into the Editor window. The entire R demo program is presented in Listing 1. Program output is displayed in the Console window. You call the program by issuing a "source" command in the Console window. You write your R program (technically a script because R is interpreted) in the Editor window. That action will launch an R Editor window like the one on the right side of Figure 1. On the top menu bar, click File | New Script.

After installation finishes, go to C:\Program Files\R-3.x.x\bin\圆4 and then double-click on the Rgui.exe file to launch an R Console shell like the one shown on the left side of Figure 1. You can accept all the installation defaults.

Navigate to that page and click on the Download link at the top of the page to launch a self-extracting executable installer (see Figure 2). Search the Web for "install R" and you'll find a link to.

You have several alternatives, including the recently released Microsoft R Server, but for simplicity I recommend using the base R system. If you're new to R and want to try out the language, the good news is that installing (and uninstalling) R is simple.

R supports nested function definitions with the "<<-" assignment operator.

R supports recursive function definitions.

R supports variable number of function arguments using the "." token.

R does not support C# style function name overloading.

R supports default parameter values using the "=" assignment operator.

R function parameters are passed by value, not by reference.

Basic R function syntax resembles C# and uses the "function" and "return" keywords.

The demo program shown running in Figure 1 illustrates each of these seven topics and gives you an idea of where this article is headed. Whenever I'm learning about program-defined functions in a new language, I want to know seven things: What's the basic syntax and return mechanism? Are parameters passed by value, by reference or both? Does the language support default parameter values? Does the language support function overloading? Does the language support variable number of arguments? Does the language support recursion? Does the language support nested definitions? In this article I present a short tutorial on writing program-defined functions in the R language. Among my developer colleagues, the three most common ways to perform data science tasks with open source tools are using the R language, using the Python language, and using the SciLab (or roughly equivalent Octave) integrated system. I think of data science as the process of programmatically analyzing data using classical statistics techniques or making predictions using machine learning techniques.
