In this R video tutorial, we will learn how to produce numeric summaries for both categorical and numerical variables in R. This tutorial explains:
• How to create frequency tables in R
• How to create contingency tables in R
• How to calculate mean, median, variance, and standard deviation in R
• How to calculate Pearson’s correlation in R
• How to calculate Spearman’s correlation with R
• How to calculate the minimum, maximum and range in R,
• How to calculate specific quantiles or percentiles in R
• How to calculate the covariance in R
