Well, this is help list for R not for Excel, maybe you shall contact
Microsoft guys. I believe that probably easiest would be to make a simple
macro in Excel.
If you want to do merging in R you shall go through help pages for
read.xls, merge, cbind, rbind and R data import/export manual.
> Dear all,
> I have an excel file that contains 6 sheets
> The analysis is repeated every 3 sheets
> Sheets 1, 2, 3:
> I want to add (horizontally) the data contained in the matrix : sheet2
> (5:end,3:end )
> of *Sheet2 * to the sheet3 such that the first element of the matrix
> *sheet2 (5:end,3:end ) *
> to occupy the location/cell sheet3(5,end+1 ) of sheet3.

> As you can see

> 2) then I add sheet1 (5:end,3:end ) to the output sheetA that results
> from the merging of sheets 2 and 3 at location sheetA((5,end+1).
> 3) The output is named ,say, sheetAA
> Similarly analysis holds for the other block of sheets 4,5,6. That is,
> Sheets 4, 5, 6:
> 1)I add sheet5 (5:end,3:end ) to sheet6 at location sheet6(5,end+1)
> 2) then I add sheet4 (5:end,3:end ) to the output sheetB that results
> from the merging of sheets 5 and 6 at location sheetB((5,end+1).
> 3) The output is named, say, sheetBB
> In my case I have a large sequence of sheets that I have to merge in
