Join Mark Niemann-Ross for an in-depth discussion in this video Code review for R, part of Database Clinic: SQLite.
- [Instructor] One of the strengths…of SQL Lite is the ability to use it with multiple languages…and graphic user interfaces.…To demonstrate this strength, I'm going to…show you a version of the process…we just completed using the Python language.…Only this time, I've rewritten it…in the R programming language.…Now I've already installed R and R Studio.…If you don't have these programming tools,…please refer to one of the other R programming courses…in the library.…This is R Studio, let's go ahead and open up…the dbjoins.r file, and you can find that…in your exercise files, chapter three,…and there's dbjoins.r, and I'm opening this up in R Studio.…
So you can see this is all R code…and I'm not going to spend a tremendous amount of time…explaining the nuances of R, but I will explain…how some of this code works.…I'm going to run the code first,…show you the results, and then we'll come back…and discuss the script.…So the first thing I'm going to do…is open up the console window a little bit.…I'm going to select all of the R script…
