[R] A challenging question: merging excel files under a specific pattern

[Stef Salvez]

Dear all,

I have an excel file that contains 6 sheets

1,2,3,4,5,6

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.

Say, that the output from this merging is sheetA. Then I want to add
horizontally the data contained in the matrix : Sheet1 (5:end,3:end )
of Sheet 1 to the sheetA * such that the first element of the matrix
*sheet1 (5: end,3:end ) to occupy the location/cell sheetA(5,end+1 )
of sheetA.

As you can see

1)I add sheet2 (5:end,3:end ) * to *sheet3 at location *sheet3(5,end+1) *

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
this way. That is,

1,2,3,4,5,6,7,8,9,10,11,12,13,…

But the logic is the same as described above.

Is there any “easy” way to do that kind of merging? . Because when you
have 13*3 =39 sheets is a bit tedious to do that merging manually.

thanks
