The R folder/directory contains each function listed in the call to the skeleton function created as an individual file with the suffix R. E.g., alpha.scale.R, omega.R, etc. Corrections to your code can be done directly to these files.

Alt key on Mac is indeed exist. And it’s called Option key.

Windows vs Mac—there are so many differences. A lot of our customers have used a PC before and then decide they want to switch to Mac for better performance, nicer design, or for better security. However, they were afraid they would have a hard time getting used to the macOS keyboard. We hear questions like, “How can I close a Window? The Mac keyboard doesn’t have the Alt + F4 shortcut.” We always give them two answers:

1. With Parallels Desktop for Mac you have the choice to use the same keyboard shortcuts you had on your PC.

2. If you want to use the Mac keyboard you will experience that the alt key is very different, as we explain in this blog post.

Where is the Alt key on a Mac keyboard?

The PC-keyboard equivalent of Alt on a Mac is called the Option key, and you’ll find the Option Key on your Mac if you go two keys to the left of the spacebar. However, the option key on a Mac keyboard is used in a different way than the alt key on a Windows PC. In terms of functionality, the alt key in Windows is often more comparable with the Command key than with the Option key on a Mac. You might be also familiar with the Ctrl and Alt keys from your PC. On your Mac keyboard, you have Command (⌘ cmd), Control (ctrl), and Option (⌥ alt) keys.

Obtaining R

R is available for Linux, MacOS, and Windows. Software can be downloaded from The Comprehensive R Archive Network (CRAN).

Startup

After R is downloaded and installed, simply find and launch R from your Applications folder.

Entering Commands

R is a command line driven program. The user enters commands at the prompt (> by default) and each command is executed one at a time.

The Workspace

The workspace is your current R working environment and includes any user-defined objects (vectors, matrices, data frames, lists, functions). At the end of an R session, the user can save an image of the current workspace that is automatically reloaded the next time R is started.

Graphic User Interfaces

Aside from the built in R console, RStudio is the most popular R code editor, and it interfaces with R for Windows, MacOS, and Linux platforms.

Operators in R

R's binary and logical operators will look very familiar to programmers. Note that binary operators work on vectors and matrices as well as scalars.

Arithmetic Operators include:

Operator	Description
+	addition
-	subtraction
*	multiplication
/	division
^ or **	exponentiation

Logical Operators include:

Operator	Description
>	greater than
>=	greater than or equal to
exactly equal to
!=	not equal to

Data Types

R has a wide variety of data types including scalars, vectors (numerical, character, logical), matrices, data frames, and lists.

Creating New Variables

Use the assignment operator <- to create new variables.

# An example of computing the mean with variables mydata$sum <- mydata$x1 + mydata$x2 mydata$mean <- (mydata$x1 + mydata$x2)/2

Functions

Almost everything in R is done through functions. A function is a piece of code written to carry out a specified task; it may accept arguments or parameters (or not) and it may return one or more values (or not!). In R, a function is defined with the construct:

function ( arglist ) {body}

The code in between the curly braces is the body of the function. Note that by using built-in functions, the only thing you need to worry about is how to effectively communicate the correct input arguments (arglist) and manage the return value/s (if any).

Importing Data

Importing data into R is fairly simple. R offers options to import many file types, from CSVs to databases.

For example, this is how to import a CSV into R.

# first row contains variable names, comma is separator # assign the variable id to row names # note the / instead of on mswindows systems mydata <- read.table('c:/mydata.csv', header=TRUE, sep=',', row.names='id')

Descriptive Statistics

R provides a wide range of functions for obtaining summary statistics. One way to get descriptive statistics is to use the sapply( ) function with a specified summary statistic.

Below is how to get the
