Shiny apps for interactive data analysis, visualization and modeling.

xplorerr

Tools for interactive data analysis

Overview

xplorerr provides a set of tools for interactive data analysis:

• Descriptive statistics
• Visualize probability distributions
• Inferential statistics
• Linear regression
• Logistic regression
• RFM Analysis
• Data visualization
  • ggplot2
  • plotly
  • rbokeh
  • highcharter

Installation

# Install release version from CRAN
install.packages("xplorerr")

# Install development version from GitHub
# install.packages("devtools")
devtools::install_github("rsquaredacademy/xplorerr")

Usage

Descriptive Statistics

Generate descriptive statistics such as measures of location, dispersion, frequency tables, cross tables, group summaries and multiple one/two way tables.

app_descriptive()

Visualize Probability Distributions

Visualize and compute percentiles/probabilities of normal, t, f, chi square and binomial distributions.

app_vistributions()

Inferential Statistics

Select set of parametric and non-parametric statistical tests. ‘inferr’ builds upon the solid set of statistical tests provided in ‘stats’ package by including additional data types as inputs, expanding and restructuring the test results. The tests included are t tests, variance tests, proportion tests, chi square tests, Levene’s test, McNemar Test, Cochran’s Q test and Runs test.

app_inference()

Linear Regression

Tools designed to make it easier for users, particularly beginner/intermediate R users to build ordinary least squares regression models. Includes comprehensive regression output, heteroskedasticity tests, collinearity diagnostics, residual diagnostics, measures of influence, model fit assessment and variable selection procedures.

app_linear_regression()

Logistic Regression

Tools designed to make it easier for beginner and intermediate users to build and validate binary logistic regression models. Includes bivariate analysis, comprehensive regression output, model fit statistics, variable selection procedures, model validation techniques and a ‘shiny’ app for interactive model building.

app_logistic_regression()

RFM Analysis

Tools for RFM (recency, frequency and monetary value) analysis. Generate RFM score from both transaction and customer level data. Visualize the relationship between recency, frequency and monetary value using heatmap, histograms, bar charts and scatter plots.

app_rfm_analysis()

Data Visualization

Tools for interactive data visualization . Users can visualize data using ‘ggplot2’, ‘plotly’, ‘rbokeh’ and ‘highcharter’ libraries.

app_visualizer()

xplorerr's Issues

Use shiny modules

Use modules to reduce repetitive code.

Associatin Rule Mining App

Add a shiny app for association rule mining/market basket analysis.

0.1.1 checklist

Prepare for release:

Template from r-lib/usethis#338

Migrate shiny app from nse2r

Migrate the shiny app from nse2r into xplorerr before the upcoming release of nse2r.

A/B testing app

Add an A/B testing app.. Depends on rsquaredacademy/inferr#52

Migrate RStudio Addin from rbin

Convert the RStudio Addin from the rbin package into a shiny app and migrate it into xplorerr.

Deploy apps

Deploy apps on cloud for live demonstration.

Split apps

Create app by package type.

• Base R
• ggplot2
• plotly
• highcharts
• rbokeh

could not find function "screener"

Tried the shiny app locally, got:

Error in screener: could not find function "screener"
  101: renderPrint [logic/logic_screen.R#3]
  100: func
   84: origRenderFunc
   83: output$screen
    3: shiny::runApp
    2: xplorerr::app_logistic_regression
    1: blr_launch_app

Add test

Use shinytest package to test the apps.

Incorrect package alias

From CRAN:

Dear maintainer,

You have file 'xplorerr/man/xplorerr.Rd' with \docType{package}, likely
intended as a package overview help file, but without the appropriate
PKGNAME-package \alias as per "Documenting packages" in R-exts.

This seems to be the consequence of the breaking change

  Using @docType package no longer automatically adds a -package alias.
  Instead document _PACKAGE to get all the defaults for package
  documentation.

in roxygen2 7.0.0 (2019-11-12) having gone unnoticed, see
<https://github.com/r-lib/roxygen2/issues/1491>.

As explained in the issue, to get the desired PKGNAME-package \alias
back, you should either change to the new approach and document the new
special sentinel

  "_PACKAGE"

or manually add

  @aliases xplorerr-package

if remaining with the old approach.

Please fix in your master sources as appropriate, and submit a fixed
version of your package within the next few months.

Best,
-k

In the shiny app, possibilty to import R files is missing

This is a request for enhancement in ds_launch_shiny_app():

1. In the app, I missed a possibility to import files from R formats, especially ".Rds" files.

2. Possibility to import datasets from current workspace would also be helpful. This would solve most of the issues related to data import features.

Check suggested packages

Check suggested packages and offer to install missing packages.

Integrate reports

Make automated reports from report package part of the following apps:

• app_descriptive()
• app_rfm_analysis()
• app_linear_regression()
• app_logistic_regression()

Download data sets

Users should be able to download:

• training and test data sets in:
  • app_linear_regression()
  • app_logistic_regression()
• RFM table in app_rfm_analysis()
