That's not what I said, I said that you need to include the commands to load the data into your working environment, I don't know with what packages you are working with but for example, if you use the readxl package to read an xlsx file, you will have to include a command like
Demo_Report <- read_excel("path\to\your\file.xlsx")
The View() command is not for loading data, it is just to visualize data that it is already loaded into memory.
