grillade

Grid sytem for shiny apps or rmarkdown document, mainly to create htmlwidgets matrix. R interface for grillade from KNACSS.

Installation

You can install the development version of grillade from GitHub with:

remotes::install_github("dreamRs/grillade")

Examples

The main function grillade() can be used in three different ways :

• in RStudio's Viewer to display {htmlwidgets} matrix
• in {shiny}, both in the UI or in the server
• in {rmarkdown} document

The default behavior is to create as many columns as elements of the grillade() :

library(grillade)

# For example, use a div with borders
box_example <- function(...) {
  tags$div(
    style = "box-sizing:border-box;border:5px solid #1C6EA4;height:100%;",
    ...
  )
}

# Construct the grid
grillade(
  box_example("Column 1"),
  box_example("Column 2"),
  box_example("Column 3"),
  box_example("Column 4"),
  box_example("Column 5")
)

You can customize the grid by providing number of columns, and specifying widths and heights of elements with knack():

grillade(
  n_col = 3,
  knack(
    cols = 2,
    box_example("Column 1")
  ),
  box_example("Column 2"),
  box_example("Column 3"),
  knack(
    cols = 2,
    rows = 2,
    box_example("Column 4")
  ),
  box_example("Column 5")
)
