1. Using R, construct time series (line) plots for both stock prices and return series. R functions ts. plot or plot can create the plot. Describe the patterns and compare the plots.

The code in R for the time series is given as below.

Step-by-step explanation:

As the complete question is not presented thus a sample code for the variables is given as below

# Libraries

library (ggplot2)

library (dplyr)

library (plotly)

library (hrbrthemes)

# Load dataset

filepath=" Your dataset path here in csv format"

data < - read. table ("filepath", header=T)

data$date < - as. Date (data$date)

# plot

data %>%

ggplot (aes (x=date, y1=value1, x=date, y2=value2)) +

geom_line (color="#69b3a2") +

ylim (0,22000) +
