Below are slides for my first R Presentation. It was a great experience working on a presentation tool outside of Microsoft Office, hoping to make more of these in the future. Enjoy!

My First R Presentation

This is my first attempt creating a presentation in R!

This is a great idea for creating reproducible presentations. I see enormous potential for these projects in the future. This is simple a sample where I can practice, experiment, and document pain-points in my learning process.

That said, let's get to it!


I definitely spent wayyyy too much time trying to add the above GIF. But I found Hao Zhu’s giphyr add-in to be the most helpful!

Slide With Code

Let’s demonstrate the benefits of creating adding code directly within a presentation. First, let’s create dummy time-series data of a random variable Y, observed from 1901 to 2000.

data <- data.frame(X = seq(1901, 2000),
                   y0 = 1:100,
                   y1 = abs(rnorm(sd = 8, n = 100))) %>% 
  rowwise() %>% 
  mutate(y2 = sin(y0), 
         Y = sum(y0, y1, y2))

Source: local data frame [6 x 5]
Groups: <by row>

# A tibble: 6 x 5
      X    y0    y1     y2     Y
  <int> <int> <dbl>  <dbl> <dbl>
1  1901     1  5.91  0.841  7.75
2  1902     2  4.12  0.909  7.03
3  1903     3 13.1   0.141 16.3 
4  1904     4  7.33 -0.757 10.6 
5  1905     5 10.1  -0.959 14.2 
6  1906     6  5.91 -0.279 11.6 


Let’s visualize the our data

I love how easy it is to incorporate plots within a presentation. As with R Markdown, I can hide the source code and only present relevant information in a neat format.

Linear Model

Let’s fit a linear regression on our data, defining the relationship between X and Y.

model <- lm(Y~X, data)

lm(formula = Y ~ X, data = data)

    Min      1Q  Median      3Q     Max 
-6.4135 -3.1194 -0.6813  1.6359 13.8722 

              Estimate Std. Error t value Pr(>|t|)    
(Intercept) -1.816e+03  2.881e+01  -63.03   <2e-16 ***
X            9.598e-01  1.477e-02   64.99   <2e-16 ***
Signif. codes:  0 '***' 0.001 '**' 0.01 '*' 0.05 '.' 0.1 ' ' 1

Residual standard error: 4.263 on 98 degrees of freedom
Multiple R-squared:  0.9773,	Adjusted R-squared:  0.9771 
F-statistic:  4223 on 1 and 98 DF,  p-value: < 2.2e-16

Evaluate Our Model

It doesn’t make much sense to evaluate the quality of our model as this is a very rudimentary example, but we can still explore how R Presentations allow us to cleanly report on our analyses.

Future Implications

I explored very basic elements of R Presentations. In the last year I’ve learned how to maneuver markdown, learning some HTML along the way. I see potential for incorporating other languages like Python, CSS, and D3.js into future presentations and look forward to using more complex data objects.

Can't wait to use this in the real world!



This is a very rudimentary example of how R Presentations can be used to make presentating fun and easy. Powerpoint is great but as someone who spends so much time in RStudio I see so many benefits of working within the same IDE where I conduct my analyses. I would like to see how easy it is to download and share R Presentations outside of RStudio - I’d like to explore the formats available for download ways that I can share presentations with others.

There are various presentation templates and customizations I’ve yet to explore, and I’ve only scratched the surface!
