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. -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Erich Neuwirth Sent: Thursday, April 24, 2008 17:22 To: R (D)COM and RExcel server related issues Subject: Re: [Rcom-l] PutArrayFromVBA: numeric vs string Handling missing values can be controlled when transferring data from Excel sheets to R.
