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,
- 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);
- Creation of subsets of data by including several conditions;
- 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;
- Manipulation of variables: concatenation/re-ordering levels of qualitative variables, transformation of quantitative variables by generic functions in R;
- Application of statistical methods (linear regression, density curve, hypothesis testing, etc.);
- Creation/management of data (named flag data) considered as atypical;
- 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.
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:
- Install the WIDEa package (using devtools package)
if(!require(devtools)){install.packages("devtools")}
devtools::install_github("PhilippeSantenoise/WIDEa")- Load the WIDEa package (once installed) and run the shiny application
require(WIDEa)
f_widea()- Update the WIDEa package if a new version is available
devtools::update_packages("WIDEa")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.
