Arguments

id

unique identifier for the module to prevent namespace clashes when making multiple calls to this shiny module.

data

a reactive expression containing an array (e.g. data.frame, matrix or data.table) or a vector indicating the dimensions of the array (e.g. c(10,10)) or column names to construct a new template for editing. If no data is supplied a template with 10 rows and columns will be generated for editing.

col_bind

additional columns to add to the data prior to loading into editor, can be either an array containing the new data, a vector containing the new column names for empty columns or a named list containing a vector for each new column.

col_edit

logical indicating whether columns can be added or removed, set to TRUE by default.

col_options

a list named with valid columns names and either c(TRUE, FALSE) for checkboxes, a vector of options for dropdowns, "date" for date input or "password" for password input.

col_stretch

logical indicating whether columns should be stretched to fill the full width of the display, set to FALSE by default.

col_names

logical indicating whether column names can be edited or a vector of column names that cannot be edited, set to TRUE by default to allow editing of column names.

col_readonly

names of columns that cannot be edited. Users will be able to edit values but these will be reverted to the original values. Column names for these column cannot be edited either.

col_factor

logical indicating whether character columns should be converted to factors prior to returning the edited data, set to FALSE by default.

row_bind

additional rows to add to the data prior to loading into editor, can be either an array containing the new data, a vector containing the new row names for empty rows or a named list containing a vector for each new column.

row_edit

logical indicating whether rows can be added or removed, set to TRUE by default.

row_index

indicates the starting index for new rows when the data supplied to DataEdit() is a subset of a larger dataset, i.e. row_index indicates the number of rows present in the parental dataset.

quiet

logical to suppress warnings when using col_options.

read_fun

name of the function to use to read in the data when a file is selected, set to read.csv by default.

read_args

a named list of additional arguments to pass to read_fun when reading in files.

...

additional arguments passed to rhandsontable.

Value

reactive expression containing the edited data.

Examples

# NOT RUN {
if (interactive()) {
  ui <- fluidPage(
    dataInputUI("input-1"),
    dataOutputUI("output-1"),
    dataEditUI("edit-1")
  )

  server <- function(input, output, session) {
    data_to_edit <- dataInputServer("input-1")
    data_edit <- dataEditServer("edit-1",
      data = data_to_edit
    )
    dataOutputServer("output-1",
      data = data_edit
    )
  }

  shinyApp(ui, server)
}
# }
