DEVELOPING DATA PRODUCTS

R Markdown Presentation & Plotly

Create a web page presentation using R Markdown that features a plot created with Plotly. Host your webpage on either GitHub Pages, RPubs, or NeoCities. Your webpage must contain the date that you created the document, and it must contain a plot created with Plotly. We would love to see you show off your creativity!

Review Criteria

The rubric contains the following two questions:

  1. Is the presentation less than two months old?
  2. Is it an interactive presentation, which appears to have been created with Plotly?

Edgar Anderson’s IRIS Data

Iris data set gives the measurements in [cm] of the variables sepal length and width and petal length and width, respectively, for 50 flowers from each of 3 species of iris. The species are Iris setosa, I. versicolor, and I. virginica.

Summary for iris database

Median :5.800 Median :3.000 Median :4.350 Median :1.300 virginica :50
Mean :5.843 Mean :3.057 Mean :3.758 Mean :1.199 NA

Max. :7.900 Max. :4.400 Max. :6.900 Max. :2.500 NA

Are there differences in petals length?

Let’s look at this image, (and p-Value): 

## [1] 4.803974e-29

Are there differences in sepals length?

## [1] 8.918734e-22

Is there a relationship between these two lengths?
