Details

Returns TRUE if the specified sheet is hidden (not visible but also not very hidden), otherwise FALSE. sheet is vectorized such that multiple worksheets can be queried with one method call. An exception is thrown if the specified sheet does not exist.

Examples

Run this code

if (FALSE) {
# Load workbook (create if not existing)
wb <- loadWorkbook("isSheetHidden.xlsx", create = TRUE)

# Write a couple of built-in data.frame's into sheets
# with corresponding name
for(obj in c("CO2", "airquality", "swiss")) {
  createSheet(wb, name = obj)
  writeWorksheet(wb, get(obj), sheet = obj)
}

# Hide sheet 'airquality'
hideSheet(wb, sheet = "airquality")

# Check if sheet 'airquality' is hidden;
# this should obviously return TRUE
isSheetHidden(wb, "airquality")

# Check if sheet 'swiss' is hidden;
# this should obviously return FALSE
isSheetHidden(wb, "swiss")


# clean up 
file.remove("isSheetHidden.xlsx")
}
