The Basics

In this chapter, you will learn all about vectors and matrices using historical stock prices for companies like Apple and IBM. You will then be able to feel confident creating, naming, manipulating, and selecting from vectors and matrices.

What is a vector?

c()ombine

Coerce it

Vector names()

Visualize your vector

Vector manipulation

Arguably the most important data structure in R, the data frame is what most of your data will take the form of. It combines the structure of a matrix with the flexibility of having different types of data in each column.

Che cos'è un data frame?

Crea il tuo primo data.frame()

Cosa può entrare in un data frame?

Usare head() e tail() sui dati con un po' di str()uttura

Dare un nome alle tue colonne/righe

Manipolazione dei data frame

Accedere e creare sottoinsiemi dei data frame (1)

Accedere e creare sottoinsiemi dei data frame (2)

Accedere e creare sottoinsiemi di data frame (3)

Aggiungere nuove colonne

Valore attuale

Valore attuale dei flussi di cassa previsti (1)

Wouldn't it be nice if there was a way to hold related vectors, matrices, or data frames together in R? In this final chapter, you will explore lists and many of their interesting features by building a small portfolio of stocks.

What is a list?

Create a list

Named lists

Access elements in a list

Adding to a list

Removing from a list
