Range.FormulaR1C1 Property 

Returns or sets the formula for the object, using R1C1-style notation in the language of the macro.

Namespace: Microsoft.Office.Interop.Excel
Assembly: Microsoft.Office.Interop.Excel (in microsoft.office.interop.excel.dll)

'Usage
Dim range1 As Range

Dim returnValue As Object
returnValue = range1.FormulaR1C1

Dim sampleValue As Object
range1.FormulaR1C1 = sampleValue

'Declaration
Property FormulaR1C1() As Object
public System.Object get_FormulaR1C1();
public void set_FormulaR1C1(System.Object);
function get FormulaR1C1() : Object;
function set FormulaR1C1(Object);

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 two-dimensional range, you can set the formula to an array of the same dimensions. Similarly, you can put the formula into an array.

Setting the formula of a multiple-cell range fills all cells in the range with the formula.
