assignment2 is a vector with numbers (16, 18, 14, 22, 27, 17, 19, 17, 17, 22, 20, 22). It provides the data for calculating the average using the myMean function.

The myMean function works by finding the average of the numbers in assignment2. It adds up all the numbers with the sum() function and then divides the total by how many numbers there are, using the length() function. This is how you figure out an average adding everything up and divide by the number of items. The function does this correctly, making it a good way to find the average of a set of numbers.

Final project - create your own R Package

Final project - create your own R Package Issaiah Jennings  In this blog post, I’ll walk you through how I created an R package, combinePredictR, to analyze the 2019 NFL Combine data. This package includes functions for cleaning, visualizing, and summarizing key player statistics, such as the 40-yard dash time. Along the way, I’ll explain the steps I took, the challenges I encountered, and how I addressed them.  Step 1: Setting Up the Package I started by setting up my R package using usethis and devtools, which are great tools for package development in R. Here's a quick rundown of what I did: I used the usethis::create_package() function to initialize the basic structure of the package. I created a new R script for each function: clean_combine_data.R: For data cleaning. plot_40yd_by_position.R: To plot the 40-yard dash times by player position. summarize_40yd_by_position.R: To create a summary table showing average, minimum, and maximum times by position. Step 2: Cleani...

The following data was collected by the local hospital. This data set contains 5 variables based on observation of 8 patients. In addition to the measurements of the patients checking in to the hospital that night, this data provides the patients' histories regarding the frequency of their visits to the hospital in the last 12 months.This data displays the measurement of blood pressure, first assessment by general doctor (bad=1, good =0) titled "first," the second assessment by external doctor (called "second"), and the last row provides the head of the emergency unit's decision regarding immediate care for the patient based on the values 0 or 1 (low = 0, high =1). The names of your variables are as follows: "Freq","bloodp","first”, " second”, ”finaldecision” > # Create vectors for each variable > Frequency <- c(0.6, 0.3, 0.4, 0.4, 0.2, 0.6, 0.3, 0.4, 0.9, 0.2) > BP <- c(103, 87, 32, 42, 59, 109, 78, 205, 135, 176...
