1a) Sum of matrices A and B:

> print(sum_result)

     [,1] [,2]

[1,]    7    5

[2,]    2    2


1b) Difference of matrices A and B:

> print(diff_result)

     [,1] [,2]

[1,]   -3   -3

[2,]   -2    4


2) Source Code: 

diag_matrix <- diag(c(4, 1, 2, 3), nrow = 4, ncol = 4)


Output:




3) Source Code:

matrix <- matrix(c(3, 1, 1, 1, 1,
                   2, 3, 0, 0, 0,
                   2, 0, 3, 0, 0,

LIS 4317 Final Project: Fuel Economy Data from the U.S Dept. of Energy

  LIS 4317 Final Project: Fuel Economy Data from the U.S Dept. of Energy Investigating the association between vehicle features and CO2 emissions in a dataset comprising fuel efficiency data is the issue statement for my final project. The objective is to ascertain the extent to which CO2 emissions differ among various vehicle classes. In order to evaluate the effects of automobiles on the environment and pinpoint possible areas where fuel efficiency regulations could be strengthened, further investigation is essential. The idea suggests that specific vehicle classes, like larger cars or ones with bigger engines, might have more CO2 emissions than other car classes. This issue is set within the larger framework of transportation research and environmental sustainability. The relationship between vehicle characteristics and emissions, particularly CO2 emissions, has been well studied in the past. Numerous techniques, such as statistical evaluations and graphics, have been used to in...

LIS 4317: Module # 10 assignment

Image
  Module # 10 assignment Time series data is important in many fields, such as finance, economics, and weather forecasting. It is defined as observations taken at repeated time intervals. Finding patterns, drawing conclusions, and coming to wise decisions all depend on the visualization of such data. First, we take a look at the 'economics' dataset that is integrated into ggplot2, which includes economic indicators for a number of years. This dataset contains variables like population, unemployment rate, and median length of unemployed. Using a time series graphic of the unemployment rate, we first investigate patterns and variations in the dataset.  By charting the median length of unemployment across time, we can see possible long-term trends or seasonal patterns. Furthermore, we explore combination visualization methods, comparing and contrasting several time series plots for investigation of correlation or comparability. The flexible framework of ggplot2 allows analysts an...
