> > "Some people familiar with R describe it as a supercharged version of > Microsoft's Excel spreadsheet software..." > It is easy to ridicule this line from the NYT article. But this is not only a very sensible comment by a smart reporter, but also one that is good for R: It is good for R because it explains the new (R) in terms of the familiar (Excel). Of course R

Hi I am using package RODBC version 1.0-1 under R version 1.7.1 on Windows XP Pro. I am having problems writing a new table to an (Excel) database using sqlSave. I connect to an empty Excel spreadsheet using odbcConnectExcel (which, I believe, uses the Microsoft Excel Driver DSN). Then I try and save a new table to the database(spreadsheet) using SqlSave, but obtain an error message. Below is

Dear Group, I hope someone out there can help me with this. I am building a Rails 2.0 application for a customer. The customer has a number of Excel spreadsheets which he would like his customers to open and complete online then submit the completed spreadsheet to him via email.

We have some Excel spreadsheets stored on our Samba 2.2.8 fileserver. The permissions are set such that some users can write to these and some cannot, but they can all read them (the world-readable bit is set). When a user with read/write access tries to open the spreadsheet, there is no problem. The user is happy and productive and outside the sun is shining. Excellent! Have a biscuit! When a

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]. N may be set in the Windows system registry, and there are a few other things that may be set in the system registry which

Even using the VBA back of Excel to create interfaces with R would make a lot of sense. Suppose I could have access to VBA macros that import and export data into R , it would be great. The R GUI series like Rattle come even closer to Excel...so a VBA _R_ExCel package might be useful to ordinary folks . Besides Excel costs money, so adding R functions to Open Office would help both of them ( if

DeaR all, I'd like to know how to create an Excel file with multiple spreadsheets from R. I searched the help files and found [1] but it is not what I want to do.

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. There exists the xlsReadWrite package on CRAN by Hans-Peter Suter,

Hi, We have a problem like I've never seen in 8 years of running Samba in production. Two users can overwrite each other's open Excel spreadsheets. It occurs very infrequently, basically randomly, never happens on a recently restarted smbd instance, and is extremely difficult to troubleshoot due to samba switching process ownership from the user to "root" shortly after
