Usage

wb_add_named_region(
  wb,
  sheet = current_sheet(),
  dims = "A1",
  name,
  local_sheet = FALSE,
  overwrite = FALSE,
  comment = NULL,
  hidden = NULL,
  custom_menu = NULL,
  description = NULL,
  is_function = NULL,
  function_group_id = NULL,
  help = NULL,
  local_name = NULL,
  publish_to_server = NULL,
  status_bar = NULL,
  vb_procedure = NULL,
  workbook_parameter = NULL,
  xml = NULL,
  ...
)
wb_remove_named_region(wb, sheet = current_sheet(), name = NULL)
wb_get_named_regions(wb, tables = FALSE, x = NULL)

Value

A workbook, invisibly.

A data frame with the all named regions in wb. Or NULL, if none are found.

Arguments

wb

A Workbook object

sheet

A name or index of a worksheet

dims

Worksheet cell range of the region ("A1:D4").

name

Name for region. A character vector of length 1. Note that region names must be case-insensitive unique.

local_sheet

If TRUE the named region will be local for this sheet

overwrite

Boolean. Overwrite if exists? Default to FALSE.

Examples

## create named regions
wb <- wb_workbook()
wb$add_worksheet("Sheet 1")

## specify region
wb$add_data(x = iris, start_col = 1, start_row = 1)
wb$add_named_region(
  name = "iris",
  dims = wb_dims(x = iris)
)

## using add_data 'name' argument
wb$add_data(sheet = 1, x = iris, name = "iris2", start_col = 10)

## delete one
wb$remove_named_region(name = "iris2")
wb$get_named_regions()
## read named regions
df <- wb_to_df(wb, named_region = "iris")
head(df)


# Extract named regions from a file
out_file <- temp_xlsx()
wb_save(wb, out_file, overwrite = TRUE)

# Load the file as a workbook first, then get named regions.
wb1 <- wb_load(out_file)
wb1$get_named_regions()
