Sorry, that's just one of my concoctions, just replace it with
a = array("1", 2, 3, "NA", 5, 6, 7, "#N/A", 9, 10)
Right now I do this:
Sub NumArr2R(VarName As String, arr)
Dim n As Integer, i As Integer
n = ismatrix(arr)
If n = 0 Then
arr = CStr(arr)
ElseIf n = 1 Then
arr(LBound(arr)) = CStr(arr(LBound(arr)))
ElseIf n = 2 Then
arr(LBound(arr), LBound(arr, 2)) = CStr(arr(LBound(arr),
LBound(arr, 2)))
Else
Stop
End If
putarrayfromvba VarName, arr
If n = 0 Or n = 1 Then
rrun VarName & "<-as.numeric(" & VarName & ")"
ElseIf n = 2 Then
rrun VarName & "<-matrix(as.numeric(" & VarName & ")," &
UBound(arr) - LBound(arr) + 1 & "," & UBound(arr, 2) - LBound(arr,
2) + 1 & ")"
End If
End Sub
Which is not very elegant...
Btw, the function StringArray crashes if the array contains a Null
value.

Handling missing values can be controlled when transferring data
from Excel sheets to R.
It is not implemented in detail when transferring data from VBA to R.
Where does makearr come from anyway?
It is neither a VBA function vor a function from RExcel.

I often use the above function to trasfer arrays to R from VBA.
Sometimes these arrays have missing values, for example, I may have
a = makearr("1", 2, 3, "NA", 5, 6, 7, "#N/A", 9, 10)
If I do
putarrayfromvba "a", a
in R I get:
> a
[1] 1 2 3 0 5 6 7 0 9 10
What should I do to get
[1] 1 2 3 NA 5 6 7 NA 9 10
instead?
Thanks
