Trouble with Excel table connection
Hello, I've been using odbcConnectExcel to connect to a spreadsheet database containing a single worksheet. Unfortunately when I try to access the data R cannot see the table. When I run sqlTables it shows the worksheet as a SYSTEM TABLE instead of as a TABLE that I can access. I am fairly certain that I am do all of the same things I've done in the past when it worked just fine.

Putting an array from excel into R Studio
Dear All, I have been using RExcel for some time and find two features especially useful: i) The ability to select part of a worksheet and put it into R ii) The way of viewing the code, the output and the alerts in separate panes. The rest of R Excel I don't really use. The major benefit for me is i) as I can use the excel as a sort of fast access database which is convenient to edit. I can

Reading a SpreadsheetML / XMLNS into R xmlns="urn:schemas-microsoft-com:office:spreadsheet
Hello, I use a software that outputs the data in a form/dialect(?) of xml (I think its called "SpreadsheetML", see below for an excerpt). It allows (admittedly) easy import of such files into Excel. I would like, however, to import it directly into R. I am familiar how to do that with standard xml-files (mostly thanks to Duncan Temple Lang's help). But I haven't found the right

"Missing value representation in Excel before
I reproduce from memory my exhaustive look into this issue. RODBC uses the Microsoft ODBC DLL's developed by Microsoft. These DLL's perform an automatic determination of column type based on the contents of the first N rows of cells in each column, where N [0,16].

Writing Excel (.xls) files on non-Windows OSs using Perl
Hi all, There have been quite a few threads in the recent months pertaining to the ability to directly write native Excel (.xls) files from R. For example, exporting R matrices and/or data frames to an Excel file, with perhaps the ability to create multiple tabs (worksheets) within a single file, with one tab/sheet per R object.
