Getting Started with R - Part 9: Lists and the [[]] operator
Lists allows us to keep a collection of various objects together
Getting Started with R - Part 8: Data frames - Construction, Subsetting and Structure
Vectors and matrices are designed to hold single types. When we need to mix data types in a tabular form we can use a data frame.
Getting Started with R - Part 7: Factors - Levels and Labels
Factors are like vectors but with values classed into levels. When vectors have a limited number of repeated values they fit the bill.
Getting Started with R - Part 6: Matrices - Captions
Adding Captions to matrices make them more readable and allows us to retain information when we subset the matrix.
