  createSheet(wb, name = obj)
  writeWorksheet(wb, get(obj), sheet = obj)
}

# Very hide sheet 'airquality'
hideSheet(wb, sheet = "airquality", veryHidden = TRUE)

# Hide sheet 'CO2'
hideSheet(wb, sheet = "CO2", veryHidden = FALSE)

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

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

# Check if sheet 'CO2' is very hidden;
# this should also return FALSE - the sheet
# is just hidden but not very hidden
isSheetVeryHidden(wb, "CO2")
