Import data into RStudio, get summary, make and save barplot, and then source as script

Introductory video on how to import a data table with info on the human genome into R via RStudio, get a summary of the table, obtain total (sum) for a column, plot some of the data in a barplot, save it as a PDF, and then save a script that you can later modify and re-run by simply sourcing the file.
The file "human-genome-info-clean.txt" is available on my GitHub. You can download it and follow along by accessing it at:

THANK YOU!!! My professor had us just drop into R without telling us any of this. I didn't even know there was programming xD
