R Markdown

This is an R Markdown document. Markdown is a simple formatting syntax for authoring HTML, PDF, and MS Word documents. For more details on using R Markdown see http://rmarkdown.rstudio.com.

When you click the Knit button a document will be generated that includes both content as well as the output of any embedded R code chunks within the document. You can embed an R code chunk like this:

summary(cars)
##      speed           dist       
##  Min.   : 4.0   Min.   :  2.00  
##  1st Qu.:12.0   1st Qu.: 26.00  
##  Median :15.0   Median : 36.00  
##  Mean   :15.4   Mean   : 42.98  
##  3rd Qu.:19.0   3rd Qu.: 56.00  
##  Max.   :25.0   Max.   :120.00

The median speed of the cars data set is 15.4.

Including Plots

You can also embed plots, for example:

Note that the echo = FALSE parameter was added to the code chunk to prevent printing of the R code that generated the plot.

library(DT)
datatable(mtcars)

Interactive Plot

Let’s add an interactive Plotly chart:

library(tibble)
mtcars <- tibble::rownames_to_column(mtcars, var = "model")

library(plotly)
## Loading required package: ggplot2
## Warning: package 'ggplot2' was built under R version 4.4.3
## 
## Attaching package: 'plotly'
## The following object is masked from 'package:ggplot2':
## 
##     last_plot
## The following object is masked from 'package:stats':
## 
##     filter
## The following object is masked from 'package:graphics':

##     layout
# Create ggplot
p <- mtcars %>% 
  ggplot(aes(x = wt, y = mpg, color = as.factor(cyl), label = model)) +  
  geom_point() +
  labs(color = "Cylinders: ") +
  theme_minimal()

# Convert ggplot to interactive plot
plotly::ggplotly(p)
