If you want to learn a simple way to analyze data with the R programming language, without all the "hard" work that too many people associate with learning R, then this is the course you want! Here's why.But First, a Warning...Before we go further, let me make something abundantly clear. This is not a course that will make you an "instant" expert in R. This is also not a course that promises you that you will learn everything R in 2 hours, just by watching the videos. And I am not suggesting that everyone (or anyone) who watches this course will like it (maybe because of my French accent). In fact, if you don't apply what you learn in this course and do the practice activities (there are 6 of them and 3 Capstone assigments), it's more than likely that you will not learn anything to analyze your data in RStudio.with that said, let me jump right in and show you...Exactly What You're GettingFirst of all, there isn't any fluff or filler, no powerpoint to fill up time. This is also not an 8 or 10 hour video course like I see sometimes, because if you're like me, you don't have 10 hours sitting to watch programming videos to get your job done. You want something that goes right to the point. That's what I am giving you...and it is easy to follow. 1 hour 54 minutes of video and you'll immediately "get" the system I use to start analyzing data in RStudio.I hear lots of people say R is a complicated language. I disagree. What used to be a steep learning curve has been made a lot simpler and more efficient with RStudio and the Tidyverse. In this Getting Started with RStudio course, you will learn everything you need to know to get started with RStudio IDE, and to clean, transform and load data with RStudio.Say goodbye to the frustrating "steep" R learning curveSay goodbye to complicated native base R commandsPlus you'll also discover …What you should never do to clear your R environment.

(Video #7)2 ways to install and load R packages in RStudio (Video #6)You need expensive and professional drivers to connect to SQL databases, right? Wrong!

(Video #16)What to do if column headers are values instead of variable names (Video #16)What to do if variables are stored in both rows and columns. (Video #16)Say goodbye to frustrations when changing long to wide or wide to long format. (Video #16)Yes, that's a lot of neat tips, but that's not all, you'll also discover...How to eliminate unnecessary coding for simple tasks like clearing the console, restarting R, or instantly finding previous commands.

You can access it immediately, from anywhere, without waiting for a DVD or physical product.oh, and in case you're wondering...THERE 'S NO CATCH!I realize that there are video courses on R in the Udemy platform that promise you to be an expert or "master" R. I also know some of these courses have 6 or 8 hours of video content, and they're priced the same, or even cheaper. So, the logical question is: "why buy this course?"The reason is simple, in my 1h 54m of video content, I show you what works now and if you're a seasoned or aspiring data analyst who want to use RStudio and R to analyze data, you don't want to go through 8 hours of content to find the commmands you need. You want the essentials, and some more, to get the job done. Because that's what it is about. Getting started with RStudio and get the job done to load, clean and transform your data to start analyze it in the most efficient way possible.Anyway, with all that said, this is a limited offer at that price. I'm constantly testing the data and I might decide to increase the price. I really don't know at that point.oh, one more thing, you're also gettingALL the Getting Started with RStudio Chear Sheets In these 3 sets of cheat sheets, you'll get one-pagers for quick reference to import, clean and transform data with RStudioGetting Started with RStudio cheat sheetImporting Data in RStudio cheat sheetTransforming (and Cleaning) Data In RStudio cheat sheetAnd by the way, you'll still protected by.UDEMY's 30-day Money Back Guaranteeof course, I am abiding by their 30-day guarantee, which states "We want you to be satisfied, so all eligible courses purchased on Udemy can be refunded within 30 days.
