Description

ggquickeda is an R Shiny app/package providing a graphical user interface (GUI) to ggplot2 and table1.

It enables you to quickly explore your data and to detect trends on the fly. You can do scatter plots, dotplots, boxplots, barplots, histograms, densities and summary statistics of one or multiple variable(s) by column(s) splits and an optional overall column.

It also has the km, kmband and kmticks geoms/stats to facilitate the plotting of Kaplan-Meier Survival curves.

Installation and Running information

# Install from CRAN:
install.packages("ggquickeda")

# Or the development version from GitHub:
# install.packages("remotes")
remotes::install_github("smouksassi/ggquickeda")

Usage

To use your pre-existing csv file launch the shiny app then navigate to your csv file and load it.

run_ggquickeda()

To use your data that is already in R launch the shiny app with the dataset object as an argument:

run_ggquickeda(myRdataset)

The best way to learn how to use ggquickeda is to load a data your are familiar with and start experimenting. Try to reproduce the steps below using the included sample_df.csv. This will give you an idea about the visuals and summaries that can be generated.

The package has also the following vignettes: 1. Introduction to ggquickeda . 2. Additional Plots and Stats with ggquickeda . 3. Visualizing Summary Data with ggquickeda .

The Export Plots and Plot Code tabs were contributed along many other additions and capabilities by Dean Attali. Once a plot is saved in the X/Y Plot tab by providing a name and hitting the Save plot star button it will become available for exporting. You can export in portrait, landscape and multiple plots per page. The Plot Code tab will let you look at the source code that generated the plot with the various options. This is helpful to get you to know ggplot2 code.

The Quick summary statistics tables using Benjamin Rich table1 package.

Here is a high level overview of some of the things that can be done with the various menus:

Inputs

Choose csv file to upload or use sample data This execute the code to load your csv file or the internal sample_data.csv:

read.csv("youruploadeddata.csv",na.strings = c("NA","."))

Once your data is uploaded the first column will be selected for the y variable(s): and the second column for the x variable:, respectively. A simple scatter plot of y versus x variables is shown. ggquickeda can handle one or more y variable(s) selections and more recently one or more x variable(s). Note that the x variable(x) should be different from those selected for y variable(s). Whether the user selects one or more y variable(s), the y variable(s) data will be automatically stacked (gathered) into two columns named yvalues (values) and yvars (identifier from which variable the value is coming from) and a scatter plot of yvalues versus x, faceted plot by yvars will be shown. Mixing categorical and continuous variables will render all yvalues to be treated as character. The order of the selected y variables(s) matters and can be changed via drag and drop. Selections can be removed by clicking on the small x. When no y variable(s) is selected a histogram (if x variable is continuous) or a barplot (if x variable is categorical) is shown.

The same applies when ore or more x variable(x) where the values are named (xvalues) and the identifier variable name is (xvars). When no x variable(s) is selected a histogram (if y variable is continuous) or a barplot (if y variable is categorical) is shown.

Data Manipulations

After selecting your y variable(s) if any and x variable you can directly proceed into data manipulation within the Inputs tab using the following subtabs. Note that the subtabs execution is sequential i.e. each subtab actions are executed in the order they appear. If the user changes an upstream action this will reset the subsequent ones.

Graph Options

Various options to tweak the plot: Controlling y and x axis labels, legends and other commonly used theme options. Adding a title, subtitle and a caption * Controlling color palette, themes, reference lines and more.

Summary/Regression functions

Additional Information

Installing the package should handle the installation of all dependencies.

The app can also be directly launched using this command:

shiny::runGitHub('ggquickeda', 'smouksassi', subdir = 'inst/shinyapp')
