matrixInput {shinyMatrix}

Create a matrix input field

Description

Use this function to create a matrix input field. Typically this would be in the 'ui.R' file of your shiny application. You can access the input via the 'input$inputId' in the server function of the shiny application. The value will always be a matrix and contain values of class 'class'.

Usage

matrixInput(
  inputId,
  label = NULL,
  value = matrix("", 1, 1),
  inputClass = "",
  rows = list(),
  cols = list(),
  cells = list(),
  class = "character",
  paste = FALSE,
  copy = FALSE,
  copyDoubleClick = FALSE,
  pagination = FALSE,
  lazy = FALSE,
  formatCell = NULL
)

Arguments

inputId

The input slot that will be used to access the value

label

label for input field

value

Initial value. Should be a matrix

inputClass

class of the matrix input html element

rows

list of options to configure rows

cols

list of options to configure cols

cells

list of options to configure cells

class

Matrix will be coerced to a matrix of this class. 'character' and 'numeric' are supported

paste

old argument

copy

old argument

copyDoubleClick

old argument

pagination

Use pagination to display matrix

lazy

lazy updating of server values. The new values are only sent to the server when no input field is visible

formatCell

format to be used for formatting cell values, i.e. ".2f" . This uses d3-format (https://d3js.org/d3-format)

Details

The parameters 'rows' and 'cols' take a list of arguments. Currently, the following arguments are supported:

n

number of rows (is calculated from value as default)

names

should row/colnames be displayed? The names are taken from value

editableNames

should row/colnames be editable

extend

Should the matrix be extended if data is entered in the last row/column?

delta

how many blank rows/cols should be added?

createHeader, updateHeader

name of javascript function to override default function to create/update table header. The function needs to have the table element and the data object as argument

getHeader

same as createHeader but with table element as only argument

Similarly, the parameter 'cells' takes a list of arguments:

editableCells

logical, should cells be editable (default 'TRUE')

Examples

matrixInput(
  "myMatrix",
  value = diag(3),
  rows = list(names = FALSE),
  cols = list(names = FALSE),
  cells = list(editableCells = FALSE)
)
