R Statistics Essential Training - Lynda.com

R is the language of big data—a statistical programming language that helps describe, mine, and test relationships between large amounts of data. Author Barton Poulson shows how to use R to model statistical relationships using graphs, calculations, tests, and other analysis tools. Learn how to enter and modify data; create charts, scatter plots, and histograms; examine outliers; calculate correlations; and compute regressions, bivariate associations, and statistics for three or more variables. Challenge exercises with step-by-step solutions allow you to test your skills as you progress.

Topics include:

• Installing R on your computer
• Using the built-in datasets
• Importing data
• Creating bar and pie charts for categorical variables
• Creating histograms and box plots for quantitative variables
• Calculating frequencies and descriptives
• Transforming variables
• Coding missing data
• Analyzing by subgroups
• Creating charts for associations
• Calculating correlations
• Creating charts and statistics for three or more variables
• Creating crosstabs for categorical variables
