counting

[montecarlo2012]

Hello.
I have a little snipe code able to tell me how many times number 1 is in the column A, I am trying to count how many time 2 is after one, but still I don't know how to say that in VBA. This is the little code:

     Sub countmontecarlo()Dim cell As Range
Dim n As Long
      For Each cell In Range("A:A")
            If cell = 1 Then
          
            n = n + 1
            End If
      Next cell
Range("b6").Value = n
End Sub

the code count 6 one's but how to count 5 times 2 under the coordinate 1-2, thank you.

Sub countmontecarlo()
Dim cell As Range
Dim lastrow As Long
Dim n As Long
Dim i As Long
    With ActiveSheet
    
        lastrow = .Cells(.Rows.Count, "A").End(xlUp).Row
        
        For i = 1 To lastrow
    
            If .Cells(i, "A").Value = 1 And .Cells(i + 1, "A").Value = 2 Then
                
                n = n + 1
            End If
        Next i
        .Range("B6").Value = n
    End With
End Sub

Thank you So much theBardd. worked perfect.

How about:

Sub counting1_2()
    Dim r As Range
    Set r = Range("A1", Range("A" & Rows.Count).End(xlUp))
    Range("[COLOR=#ff0000]B5[/COLOR]").Value = WorksheetFunction.CountIf(r, 1)
    Range("[COLOR=#ff0000]B6[/COLOR]").Value = Evaluate("=SUMPRODUCT((" & r.Address & "=1)*(" & r.Offset(1).Address & "=2))")
End Sub

 

[Rick Rothstein]

How about:

    Range("[COLOR=#ff0000]B6[/COLOR]").Value = Evaluate("=SUMPRODUCT((" & r.Address & "=1)*(" & r.Offset(1).Address & "=2))")

Since the Evaluate function processes non-text functions as arrays (when an array of values are involved) natively, you can use the SUM function instead of the SUMPRODUCT function for the expression you are giving it. Also, you do not need to include the equal sign for the Evaluate function.

Range("B6").Value = Evaluate("SUM((" & r.Address & "=1)*(" & r.Offset(1).Address & "=2))")

Thank you DanteAmor.

Mr. Rick Rothstein My personal admiration for you Sir, Thank you, So much for your input.

 

[montecarlo2012]

As you can see, at the beginning the post has a little Matrix, what I was trying to request is to count the value of following position for each number. I don't know if make sence,
like how many times 3 is after 2, and so on, but I really apreciate the answers, I am working now trying to find the way, for me is really dificult, but....
