What is Data Science?

The best description of what Data Science is given by Wickham and Grolemund in their book R for Data Science.

Data Science

If you have not already done so you should

1. Download and install R from r-project.org

2. Download and install RStudio rstudio.com

3. Get an RStudio Cloud account RStudio Cloud

Read Chapter 1 What is data science?

Read Chapter 2 and 3 to get strart with ggplot2

Read Chapter 27 to become familiar with R Notebooks and R Markdown.

Install the packages

install.packages("tidyverse")

We will be practicing Reproducible Research using R Markdown and R Projects.

Or as Hadley Wickham describes it, start "Living a reproducible life."

1. R Scripts
2. R Notebooks
3. R Projects

Try all of the code in Chapter 3.

You can also embed plots, for example:

Note that the echo = FALSE parameter was added to the code chunk to prevent printing of the R code that generated the plot.
