Command Line Tools installs a C compiler, GCC, and many other helpful utilities that are commonly used in the unix world. Because the package has to download from Apple, it may take a while depending on your internet connection. Honestly, using Homebrew is much easier and is probably better for most users, but admittedly itвЂ™s not for everyone.ДЇor those who donвЂ™t have the Command Line Tools package either with or without Xcode installed yet, itвЂ™s fairly simple: Open Terminal and type вЂxcode-select вЂ“installвЂ™, or you can do it from Xcode by opening XCode, then go вЂњPreferencesвЂќ and to the downloads section, and choose вЂњInstall Command Line ToolsвЂќ, or you can get it from the Apple Developer Site as described here.

This approach is going to build and install wget in Mac OS X from source, this means youвЂ™ll need Xcode (App Store link), or at least and the Unix command line dev tools installed on the Mac, but it has the benefit of eliminating the need of a package manager like Homebrew or MacPorts.

Then use args, args, etc.The command line tool wget lets you retrieve a group of files from FTP and HTTP protocols, itвЂ™s a very useful utility for web developers and powerusers to have around because it lets you do things like perform quick and dirty site backups and even mirror websites locally.

You can args=commandArgs(trailingOnly=TRUE) to get variables from command line.

The -vanilla tells Rscript to run without saving or restoring anything in the process.

Tells computer where to find bash for running our code.

Run chmod +x filename.R to make the file executable.

R as the file extension to make it clear that its a shell script

Use comments to describe what is going on in the code.

Create a commented header to state the title of the script, author, any inputs and outputs.

Include a shebang line as the first line.

You can find my version of the project on GitHub.

Please take the time to follow along on your own computer.

WeвЂ™ll see how we can integrate this new script with our earlier analysis.Д®ven if youвЂ™re only watching this video to learn more about R and donвЂ™t know what a 16S rRNA gene is, IвЂ™m sure youвЂ™ll get a lot out of todayвЂ™s video.

In todayвЂ™s episode of Code Club, IвЂ™ll show you how to create an executable R script that can be run without starting, takes input, and uses good reproducible practices.

But it isnвЂ™t automated and isnвЂ™t an approach that will play well with a Makefile. This is a bit like how we could run bash commands from the command line interface. Typically, when people analyze data in R, they enter commands at the prompt in RStudio.

If not, I have several tutorials at the website that you can use for free to learn a lot of fundamentals for analyzing microbiome and other types of data. This will move us closer to quantifying how sensitive and specific amplicon sequence variants are for differentiating bacterial populations in microbiome analyses. Now, weвЂ™re going to switch tools and start working with data in R.

Are you ready for some R? To this point, IвЂ™ve been showing you how you can process data files in bash using reproducible practices.
