Intro to Data Visualization with R & ggplot2

In this webinar, we will provide an introduction to data visualization with the ggplot2 package. The focus of the webinar will be using ggplot2 to analyze your data visually with a specific focus on discovering the underlying signals/patterns of your business.

The R programming language is experiencing rapid increases in popularity and wide adoption across industries. This popularity is due, in part, to R’s rich and powerful data visualization capabilities. While tools like Excel, Power BI, and Tableau are often the go-to solutions for data visualizations, none of these tools can compete with R in terms of the sheer breadth of, and control over, crafted data visualizations.

As an example, R’s ggplot2 package provides the R programmer with dozens of print-quality visualizations – where any visualization can be heavily customized with a minimal amount of code.

In this talk attendees will learn how to:
• Craft ggplot visualizations, including customization of rendered output.
• Choose optimal visualizations for the type of data and the nature of the analysis at hand.
• Leverage ggplot2’s powerful segmentation capabilities to achieve “visual drill-in of data”.
• Export ggplot2 visualizations from RStudio for use in documents and presentations.

I would suggest everyone beginning with ggplot2 to go through this 1hr vedio, it will save you a lot of time understanding the basics.

[AliAwadh]

The seventh question, I believe the labs should be as:
labs(x = "Age", y = "Density"), and
labs(x = "Age", y = "Survived Count")

This video is literally PERFECT for ggplot2 beginners! In only one hour, you'll learn the basics of ggplot2 R coding and you'll end up falling in love with ggplot2 (I thought this language was weird and not intuitive at first, but after this video I think it's very useful and practical to visualize more accurate data plots!)

This was amazing - thanks. It was, literally, the first time I've ever coded anything in my life, I've wanted to learn about data vis stuff for sports analytics for a long time and this video was the perfect introduction.

If anyone is in a similar position to myself, and has zero ! previous knowledge of R or programming, and wants to learn about data vis, I'd just start with this video. The only thing I needed to hit google for was to learn how to import the dataset into RStudio (yes, really).

Thank you!

I need some help with my R language biostatistics and I'm glad to pay the affordable R tutorial through Zoom or any other platform.

[michaelrockinger]

Show really starts after 25min. You should have discussed passengerid and name when you discussed the variables. Is ggplot smart to use factors for visualization? In a few days i will be desperate to remember that i need to factor to get certain visu. It should be the programmer to have contol not the program. No? Is it really sooo complicated to put % in the plot? Not good publicity for such a great package as ggplot.

[mursyidhb]

Thanks Dave... I think the way you present the code and interpreting the result is awesome. even I have just new to ggplot2, the presentation bring me as if we have so familiar with the code. You make R is not that difficult.

[ruizhang]

Thanks for the tutorial! Small caveats on the density plot and the histogram towards the end. The axes are mislabeled. Y should be probability density or counts, while X should be age

[ayasuniverse]

THIS IS ABSOLUETELY ONE OF THE BEST TUTORIALS ON CODING THAT I'VE EVER SEEN !!!! THANK YOUUU !! UP UP UP

[Bkoerier]

what a load of unnecessary talking.... 25 minutes of not needed introduction. 5 minutes to tell why passengerID and name are not relevant.... get to the point already...

DATA SCIENCE DOJO Piliz share the R code, my not running properly

[joanabucheri]

Thank you for this video, it was indeed helpful. Didn't have sufficient knowledge in ggplots but now i do. Thanks a lot!

[saurabhyelmame]

Why the column names are converted to factors in 32:38 ?
I tried using them without converting to factors.
Some were executed but some gave errors.

[bikashpokharel]

Wait a minute, I am gonna update my linked In bio to R expert

[Jxdemelo]

Simply exceptional. Thank you. I'm hooked. And I'm not even a Data Scientist. If I was 20 years younger, I'd get into this field.

[maurocarvalho]

Great presentation! Thanks for making ggplot2 easier to be understood.

[WahranRai]

46:08 May be instead of using copy and paste, we could use, for example:
ggplt = ggplot2(titanic, aes...) and add layers to that
ggplt +
theme_bw().+
labs()....

[najibbht]

Super helpful and crystal clear intro. Thank you very much!

[darren]

Mistakes in your code 162, 163, 171 and 172. The x axis should be "Age" and y axis should be "Survived". By the way, great tutorial!
