Use the given code below to answer the questions.

Q1 Import Netflix stock prices, instead of Apple.

Hint: Insert a new code chunk below and type in the code, using the tq_get() function above. Replace the ticker symbol. Find ticker symbols from Yahoo Finance.

Q2 How many shares of the stock were traded on January 13, 2017?

The shares on January 13, 2017 opened with 131.15, had a high of 133.93, and a low of 130.58 It closed with 133.70 and adjusted 133.70 in total.

Q3 Stock prices in this data would be a good example of numeric data. Character and logical are two other basic data types in R. List one example of character data and one example of logical data.

Hint: Watch the video, “Basic Data Types”, in DataCamp: Introduction to R for Finance: Ch1 The Basics.

Character Data is composed of strings of characters and examples include open ended questions, such as “how are you”.

Logical Data includes all required entities, attributes, key groups, and relationships that represent business information and define business rules. Examples can include entity names and attribute names.

Q4 Plot the closing price in a line chart.

Hint: Insert a new code chunk below and type in the code, using the ggplot() function above. Revise the code so that it maps close to the y-axis, instead of adjusted.

For more information on the ggplot() function, refer to Ch2 Introduction to ggplot2 in one of our e-textbooks, Data Visualization with R.

Q5 From the chart you created in Q4, briefly describe how the Netflix stock has performed since the beginning of 2019.

In the beginning of 2019, Netflix began with a stock point of approximately 230. During the course of the year, the stock has risen to a peak of approximately 480, and finished the year with approximately 470.

Q6 Import two stocks: Netflix and Amazon for the same time period.

Hint: Insert a new code chunk below and type in the code, using the tq_get() function above. You may refer to the manual of the tidyquant r package. Or, simply Google the tq_get function and see examples of the function’s usage.
