Java for Mac OS X 10.9.5: A Comprehensive Guide

Macs come with Python 2.7, but if you're just starting out, it's not a bad idea to upgrade to Python 3.x. To install, simply click on the download link (RStudio.dmg) and drag the RStudio application to your Applications folder. Alternatively, search Google for 'R studio' and follow the links to download the Open Source version of RStudio Desktop.

One of the best things about RStudio is that it provides a nice graphical interface for using R. It makes it much less scary to use R for making graphs, as you get instantaneous feedback. You can also install packages like VennDiagram, which offers colorful and interactive visualizations.

To install R, search Google for 'R' and follow the links to a CRAN download page of your choosing. Download the pre-compiled binary by clicking on the 'Download R for (Mac) OS X' link. R is free software that supports a multitude of statistical and graphic applications.

Installing Java

Java comes bundled with Mac OS X, but you may need to update it to the latest version. To do this, open the Terminal application and enter the following command:

```

java -version

```

This will output the current version of Java installed on your system. If you're running an older version, you can update it by downloading the latest version from Oracle's website.

Installing Xcode

Xcode is a free development environment provided by Apple that allows you to build applications for Mac computers or iOS devices. To install Xcode, open the App Store application and search for 'Xcode'. Click on the 'Get' button to download and install the latest version.

Additional Tools and Utilities

RStudio also requires some additional tools and utilities to be installed. These include:

* `make`: A software tool provided by Apple that is used for building applications.

* `ngs`: A package manager for installing scientific computing packages.

To install these tools, follow these steps:

1. Open the Terminal application and enter the following command:

```

export PATH=$HOME/local/bin:$PATH

```

2. Save the updated profile by pressing 'esc' then ':w' then ':q'.

3. Create an alias to open connections to a computation resource using the following commands:

```bash

alias ll='ls -l'

```

These are just a few examples of how you can customize your terminal experience.

In conclusion, installing Java and RStudio on Mac OS X 10.9.5 is a relatively straightforward process that requires some basic knowledge of Terminal commands. With these tools installed, you'll be able to take advantage of the many statistical and graphic applications available for R, as well as build your own custom applications using Xcode.
