It tells us that the square root of 9 is 3.
#COMPREHENSIVE META ANALYSIS SOFTWARE FOR MAC CODE#
The console is where all the R code is entered and then run. The heart of R Studio, however, is the left side, where you can find the Console.
This pane serves several functions for example, it is used to display files on your computer, show plots and installed packages, and to access the help pages. In the bottom right corner, you can find the Files, Plots, Packages and Help pane. In the upper right corner, we have the Environment pane, which displays objects that we defined (i.e. saved) internally in R. The first time you open R Studio, it will probably look a lot like in Figure 2.1.
#COMPREHENSIVE META ANALYSIS SOFTWARE FOR MAC INSTALL#
Simply download and install the free version of R Studio Desktop.
There are also versions of R Studio for which you have to buy a license, but this is definitely not required for our purposes. By the time you install R, there may already be a higher version available, and it is advised to always install the latest version.Īfter you have downloaded and installed R, you can download “R Studio Desktop” from the R Studio website. For this book, we are using R version 4.0.3.
#COMPREHENSIVE META ANALYSIS SOFTWARE FOR MAC UPDATE#
It is therefore helpful to update the R version regularly, maybe roughly every year, by re-installing R. When your R version becomes too outdated, it may happen that some things will not work anymore. R is regularly updated, meaning that new versions become available. An important detail about R is its version.

The type of R you have to download depends on whether you are using a Windows PC or a Mac.
#COMPREHENSIVE META ANALYSIS SOFTWARE FOR MAC ARCHIVE#
It can be downloaded from the Comprehensive R Archive Network, or CRAN, website. First, we therefore have to install the latest R version. But R Studio is not identical with R it requires that R software is already installed on your computer. R Studio is an interface which allows us to write R code and run it in an easy way. Let us go through the necessary steps to set up R and R Studio for our first coding endeavors. If you have never used R before, bear with us. If you have installed R Studio on your computer already, and if you are an experienced R user, none of this might be new for you. In this chapter, we will focus on how you can install R and R Studio on your computer. That being said, it is time to get started. But it is a superpower that everyone can learn, provided some time and effort.
Whether you are working in academia or at a company, the things you can do in R will often seem like a superpower to others. The R community is rapidly expanding each and every year, and R ’s appeal is so large that even the New York Times found it newsworthy to report on it ( Vance 2009). R is the most versatile, comprehensive and most frequently used statistical programming language. We want to assure you that learning R is worth it. In the preface, you can find an entire section in which we describe a few things you can do if you get stuck. Frustration is an unpleasant, but natural part of this process. Like any language, R has to be learned, and it needs practice to become a proficient user. R, on the other hand, has none of these limitations but can require more background knowledge. GUIs allow you to perform data analyses just by clicking a few buttons, but you are ultimately limited to the functionality that the developers have deemed important. Hadley Wickham, one of the most important figures in the R community, once stressed that R is fundamentally different to Graphical User Interface (GUI) based software for statistics ( Grolemund 2014, Foreword). Nevertheless, it is still harder to work with R compared to other data analysis programs you may have used before. We will also get to know an extremely powerful computer program that we can use to make writing and running R code much less cumbersome. Over the last two decades, thousands of intelligent people all around the world have contributed ways to make working with R easier and more convenient for its users. That is understandable, but there is no reason to worry. Possibly, this is your first-ever exposure to programming, and you might feel a little anxious. N this chapter, we begin our journey into the R universe.
