shiny-explore-dataset

Shiny Application for exploring new datasets.

Hosted on shinyapps.io

The app is currently hosted at https://kercheval.shinyapps.io/shiny-explore-dataset/.

shinyapps.io gives a limited number of uptime hours per month at the free level, so it might be sporatically unavailable.

Run Locally

This app utilitizes my rtools package which is a personal library of code that I typically re-use.

So, if you want to run locally, among the other libraries that are imported, you'll have to install rtools from github

devtools::install_github('shane-kercheval/rtools')

Notes On How to Use

The typical dataset to use with this app is a tidy dataset.

In tidy data:

  • Each variable forms a column.
  • Each observation forms a row.
  • Each type of observational unit forms a table.

Loading datasets

loading

  • Loads either preloaded datasets, or either a .csv or .RDS
    • The downside of loading a CSV is that the app won't be able to use ordered factors, or anything that isn't automatically detected by read.csv().

Variable Plots

  • Filtering Notes
    • when the filter is enabled, the header will turn green
    • when the filter is enabled and changes have been made but not applied, the header will turn red
    • sliders for filtering numeric data are inclusive
  • WARNING: enabling the filters removes all of the NA/missing values from each of the numberic variables even if the sliders are still set to the min/max values. Additionally, filtering numeric data removes the data from the dataset before it is graphed, changing the underlying distribution (unlike the x/y zoom min/max controls).
