Set column widths in Xlsx files

Usage

set_xlsx_colwidths(
  xlsxFile,
  sheet = 1,
  cols = seq_along(widths),
  widths = 11,
  ...
)

Arguments

xlsxFile: character filename to a file with ".xlsx" extension, or Workbook object defined in the openxlsx package. When xlsxFile is a Workbook the output is not saved to a file.
sheet: integer sheet number or character sheet name, passed to openxlsx::setColWidths() indicating the worksheet to affect.
cols: integer vector indicating the column numbers to affect.
widths: numeric vector indicating the width of each column defined by cols.
...: additional arguments are passed to openxlsx::setColWidths().

Value

Workbook object as defined by the openxlsx package is returned invisibly with invisible(). This Workbook can be used in argument wb to provide a speed boost when saving multiple sheets to the same file.

Details

This function is a light wrapper to perform these steps from the very useful openxlsx R package:

Examples

# write to tempfile for examples
if (check_pkg_installed("openxlsx")) {
   out_xlsx <- tempfile(pattern="writeOpenxlsx_", fileext=".xlsx")
   df <- data.frame(a=LETTERS[1:5], b=1:5);
   writeOpenxlsx(x=df,
      file=out_xlsx,
      sheetName="jamba_test");

   ## By default, cols starts at column 1 and continues to length(widths)
   set_xlsx_colwidths(out_xlsx,
      sheet="jamba_test",
      widths=rep(20, ncol(df))
   )
}
