`htmlwidget` for a Parallel Coordinates Plot

Create a parallel coordinates plot, using `htmlwidgets` package and `d3.js`.

parallelPlot

'parallelPlot' is:

• an interactive parallel coordinates plot (thanks to the d3.js);
• an HTML widget for R that render in various contexts including the R console, 'R Markdown' documents, and 'Shiny' web applications (thanks to the htmlwidgets package);
• a Shiny widget that can be updated programmatically and whose some actions can trigger reactions.

As an example, a Shiny application is available on shinyapps.io.

Installation

You can install this package from CRAN, or the development version from GitLab:

# CRAN version
install.packages('parallelPlot')

# Or GitLab version
if (!require('devtools')) install.packages('devtools')
devtools::install_gitlab(host = 'https://gitlab.com', repo = 'drti/parallelPlot', subdir = 'htmlwidget')

Example

library(parallelPlot)
categorical <- list(cyl = c(4, 6, 8), vs = c(0, 1), am = c(0, 1), gear = 3:5, carb = 1:8)
parallelPlot(mtcars, categorical = categorical, refColumnDim = "cyl")
