bah*_*kev 16 vba pivot-table r excel-vba reshape2
我正在适应一项新工作,我与同事分享的大部分工作都是通过MS Excel进行的.我经常使用数据透视表,因此需要"堆叠"数据,恰好是R melt()中的reshape(reshape2)包中的函数输出,我已经依赖它了.
任何人都可以让我开始使用VBA宏来完成此任务,还是已经存在？
宏的轮廓将是:
换句话说,输出看起来与在R中简单地执行这两行的输出完全相同:
require(reshape)
melt(your.unstacked.dataframe, id.vars = 1:4)
这是一个例子:
# unstacked data
> df1
Year Month Country Sport No_wins No_losses High_score Total_games
2 2010 5 USA Soccer 4 3 5 9
3 2010 6 USA Soccer 5 3 4 8
4 2010 5 CAN Soccer 2 9 7 11
5 2010 6 CAN Soccer 4 8 4 13
6 2009 5 USA Soccer 8 1 4 9
7 2009 6 USA Soccer 0 0 3 2
8 2009 5 CAN Soccer 2 0 6 3
9 2009 6 CAN Soccer 3 0 8 3
# stacking the data
> require(reshape)
> melt(df1, id.vars=1:4)
Year Month Country Sport variable value
1 2010 5 USA Soccer No_wins 4
2 2010 6 USA Soccer No_wins 5
3 2010 5 CAN Soccer No_wins 2
4 2010 6 CAN Soccer No_wins 4

我有两篇帖子,包括可用的代码和可下载的工作簿,在我的博客上使用Excel/VBA执行此操作:
http://yoursumbuddy.com/data-normalizer
http://yoursumbuddy.com/data-normalizer-the-sql/
这是代码:
'Arguments
'List: The range to be normalized.
'RepeatingColsCount: The number of columns, starting with the leftmost,
' whose headings remain the same.
'NormalizedColHeader: The column header for the rolled-up category.
'DataColHeader: The column header for the normalized data.
'NewWorkbook: Put the sheet with the data in a new workbook?
'
'NOTE: The data must be in a contiguous range and the
'columns that will be repeated must be to the left,
'with the columns to be normalized to the right.
Sub NormalizeList(List As Excel.Range, RepeatingColsCount As Long, _
NormalizedColHeader As String, DataColHeader As String, _
Optional NewWorkbook As Boolean = False)
Dim FirstNormalizingCol As Long, NormalizingColsCount As Long
Dim ColsToRepeat As Excel.Range, ColsToNormalize As Excel.Range
Dim NormalizedRowsCount As Long
Dim RepeatingList() As String
Dim NormalizedList() As Variant
Dim ListIndex As Long, i As Long, j As Long
Dim wbSource As Excel.Workbook, wbTarget As Excel.Workbook
Dim wsTarget As Excel.Worksheet
With List
'If the normalized list won't fit, you must quit.
If .Rows.Count * (.Columns.Count - RepeatingColsCount) > .Parent.Rows.Count Then
MsgBox "The normalized list will be too many rows.", _
vbExclamation + vbOKOnly, "Sorry"
Exit Sub
End If
'You have the range to be normalized and the count of leftmost rows to be repeated.
'This section uses those arguments to set the two ranges to parse
'and the two corresponding arrays to fill
FirstNormalizingCol = RepeatingColsCount + 1
NormalizingColsCount = .Columns.Count - RepeatingColsCount
Set ColsToRepeat = .Cells(1).Resize(.Rows.Count, RepeatingColsCount)
Set ColsToNormalize = .Cells(1, FirstNormalizingCol).Resize(.Rows.Count, NormalizingColsCount)
NormalizedRowsCount = ColsToNormalize.Columns.Count * .Rows.Count
ReDim RepeatingList(1 To NormalizedRowsCount, 1 To RepeatingColsCount)
ReDim NormalizedList(1 To NormalizedRowsCount, 1 To 2)
End With
'Fill in every i elements of the repeating array with the repeating row labels.
For i = 1 To NormalizedRowsCount Step NormalizingColsCount
ListIndex = ListIndex + 1
For j = 1 To RepeatingColsCount
RepeatingList(i, j) = List.Cells(ListIndex, j).Value2
Next j
Next i
'We stepped over most rows above, so fill in other repeating array elements.
For i = 1 To NormalizedRowsCount
For j = 1 To RepeatingColsCount
If RepeatingList(i, j) = "" Then
RepeatingList(i, j) = RepeatingList(i - 1, j)
End If
Next j
Next i
'Fill in each element of the first dimension of the normalizing array
'with the former column header (which is now another row label) and the data.
With ColsToNormalize
For i = 1 To .Rows.Count
For j = 1 To .Columns.Count
NormalizedList(((i - 1) * NormalizingColsCount) + j, 1) = .Cells(1, j)
NormalizedList(((i - 1) * NormalizingColsCount) + j, 2) = .Cells(i, j)
Next j
Next i
End With
'Put the normal data in the same workbook, or a new one.
If NewWorkbook Then
Set wbTarget = Workbooks.Add
Set wsTarget = wbTarget.Worksheets(1)
Else
Set wbSource = List.Parent.Parent
With wbSource.Worksheets
Set wsTarget = .Add(after:=.Item(.Count))
End With
End If
With wsTarget
'Put the data from the two arrays in the new worksheet.
.Range("A1").Resize(NormalizedRowsCount, RepeatingColsCount) = RepeatingList
.Cells(1, FirstNormalizingCol).Resize(NormalizedRowsCount, 2) = NormalizedList
'At this point there will be repeated header rows, so delete all but one.
.Range("1:" & NormalizingColsCount - 1).EntireRow.Delete
'Add the headers for the new label column and the data column.
.Cells(1, FirstNormalizingCol).Value = NormalizedColHeader
.Cells(1, FirstNormalizingCol + 1).Value = DataColHeader
End With
End Sub
你这样称呼它:
Sub TestIt()
NormalizeList ActiveSheet.UsedRange, 4, "Variable", "Value", False
End Sub

微软最近推出了Power Query,这是一个Excel加载项,它为Excel中的数据操作添加了许多有趣的功能和功能,包括您正在寻找的内容.
加载项中的实际功能称为"Unpivot Columns",本文将对此进行说明.这是它的要点:
