WIDEa
(Web Interface for Data Exploration)

Description

WIDEa is R-based software aiming to provide users with a range of functionalities to explore, manage, clean and analyse "big" environmental and (in/ex situ) experimental data. These functionalities are the following,

1. Loading/reading different data types: basic (called normal), temporal, infrared spectra of mid/near region (called IR) with frequency (wavenumber) used as unit (in cm-1);
2. Creation of subsets of data by including several conditions;
3. Interactive data visualization from a multitude of graph outputs (grouped by a qualitative/quantitative variable): 2D/3D scatter-plot, box-plot, hist-plot, bar-plot, correlation matrix;
4. Manipulation of variables: concatenation/re-ordering levels of qualitative variables, transformation of quantitative variables by generic functions in R;
5. Application of statistical methods (linear regression, density curve, hypothesis testing, etc.);
6. Creation/management of data (named flag data) considered as atypical;
7. Study of model results for different strategies: calibration (checking assumptions on residuals), validation (comparison between measured and fitted values). The model considers an error term following a Gaussian distribution and can be written in different forms: (non) linear, mixed effects, main/interaction effects, weighted residuals.

Installation and usage

A detailed description about how to install and use WIDEa is available from the pdf file named WIDEa_manual.

Copy/paste the code below into a R console to:

1. Install the WIDEa package (using devtools package)

if(!require(devtools)){install.packages("devtools")}
devtools::install_github("PhilippeSantenoise/WIDEa")

2. Load the WIDEa package (once installed) and run the shiny application

require(WIDEa)
f_widea()

3. Update the WIDEa package if a new version is available

devtools::update_packages("WIDEa")

R version and packages

A R version 3.5 or greater is required before installing WIDEa (R link).
WIDEa used functions of several R packages: arrangements, car, colourpicker, data.table, DT, grDevices, htmltools, htmlwidgets, janitor, magrittr, plotly, RColorBrewer, scales, shiny, shinyBS, shinybusy, shinyFiles, shinyjs, shinythemes, stats.

WIDEa installation on macOS

Hey Philippe,

I had to manually install WIDEa because the WIDEa_setup_macos.app could not be opened on my Mac.

In the manual install, V8 did not install if you do not have installed the underlying library. Or you give the environment variable Sys.setenv(DOWNLOAD_STATIC_LIBV8=1) before installation, which worked for me.

Kind regards,
Matthias
