Module 39 Rmarkdown dashboards with flexdashboard

 

1. Install Rmarkdown.

2. Start a new Rmarkdown file. In RStudio, pick the “From Template” option. Pick flexdashboard. Name your file “dashboard.Rmd”.

3. Set up your work space by loading the ggplot2, dplyr, flexdashboard, leaflet.extras, leaflet, and lubridate packages.

3. Read in some violence data by running

if(!file.exists('violence.RData')){
  download.file('https://github.com/databrew/intro-to-data-science/blob/main/data/GEDEvent_v21_1.RData?raw=true', 'violence.RData')
}
load('violence.RData')
vio <- GEDEvent_v21_1; rm(GEDEvent_v21_1)

4. Take a look at some details on the data here: https://ucdp.uu.se/downloads/ged/ged211.pdf

5. Take a look at the head of your data. What is the unit of observation?

6. Make a dashboard showing some interesting aspect of violence. It should include at least 3 panels, of which at least 1 should be a map. Be creative.
