Excel Developer Reference 
Returns or sets the formula for the object, using R1C1style notation in the language of the macro. Read/write Variant.
Syntax
expression.FormulaR1C1
expression A variable that represents a Range object.
Remarks
If the cell contains a constant, this property returns the constant. If the cell is empty, the property returns an empty string. If the cell contains a formula, the property returns the formula as a string, in the same format in which it would be displayed in the formula bar (including the equal sign).
If you set the value or formula of a cell to a date, Microsoft Excel checks to see whether that cell is already formatted with one of the date or time number formats. If not, the number format is changed to the default short date number format.
If the range is a one or twodimensional range, you can set the formula to a Visual Basic array of the same dimensions. Similarly, you can put the formula into a Visual Basic array.
Setting the formula of a multiplecell range fills all cells in the range with the formula.
Example
This example sets the formula for cell B1 on Sheet1.
