🔧 Requirements

Please install the required R packages before running the script:

install.packages("dplyr") install.packages("ggplot2")

Execution

Update the file path in the script to match the location of your survey CSV file on your system. Locate this line in the R script:

read.csv("E:/projects/R_project/survey.csv")

• Change the path to point to your own file location. For example:

read.csv("C:/Users/YourUsername/Documents/SurveyData/survey.csv")

• Run the script in R or RStudio by executing the following command:

source("E:/projects/R_project/Survey_Data_Analysis.R")

This will process the data, generate plots, and export results to the Survey_Analysis_Graphs folder. After execution, find all the generated files in your Downloads folder:

C:/Users/YourUsername/Downloads/Survey_Analysis_Graphs/
