Getting Started with typeR

Introduction

Welcome to the typeR package!

In this vignette, you’ll learn how to install the package, what it’s designed for, and how to use its core functionality. Whether you’re a beginner or an advanced R user, this guide will help you get started on the right foot.

This package is designed to simulate typing effects in R scripts for presentations and tutorials.

Installation

If you haven’t already, you can install the package. As soon as it becomes available on CRAN:

install.packages("typeR")

Install the development version on GitHub:

# Install devtools package if not already installed
if (!requireNamespace("devtools", quietly = TRUE)) {
  install.packages("devtools")
}

# Install from GitHub
devtools::install_github("fgazzelloni/typeR")

After installation, load the package:

library(typeR)

Quick Start Example

Let’s dive into a simple example to show you how typeR works in practice.

Example with a custom R script

The typeR() function can simulate typing an R script line by line in the R console. Here’s a basic example:

library(typeR)

# Create a test script for demonstration
writeLines(c(
  "# Testing typeR",
  "x <- 1:10",
  "y <- x*2",
  "plot(x, y)"
), "test_script.R")

# Simulate typing the script
typeR("test_script.R", delay = 0.05)

And here’s what the output looks like:

typeR demo
typeR demo

New in Version 0.2.0: typeRun()

For live code execution with typing animation, see the dedicated vignette:

vignette("typerun-demo", package = "typeR")

This vignette covers how to use the typeRun() function, which types out and executes R code in real-time.

Check out the function reference documentation for details on the available parameters and their usage.

Next Steps

Now that you’re up and running with typeR, here are a few suggestions for further learning:
