I?ve got an Excel workbook with about 30 worksheets. Each worksheet has 10000 rows of data over 30 columns. I?d like to read the data from each worksheet into a dataframe or matrix in R for processing. Normally, I use read.csv when interacting with Excel but I?d rather manipulate a multisheet workbook directly than set about splitting the original workbook and saving down each part as a csv.

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 list, I just installed the rcom package and tried to read/give out some values from/to Excel. Altogether it works great... but nevertheless I don't know how the syntax works or in other words: "Which command needs which parameters?"

One can import data from Excel ODBC source, but of course it is user's responsibility to ensure that the data are consistent. Each worksheet in the Excel workbook can be accessed as a table (for example, for Sheet1, you should type "select * from [Sheet1$]". The worksheet should have first row containing the column names, and the data rows should follow (the

I am having a problem in reading the columns from an xls file.

Hans-Peter and other R developers, How are you? Have you made any progess with embedding Url's in Excel? Well, I have been busy thinking of more things for you to do;) My colleagues in the lab are not R literate, and some are barely computer literate, so I give them everything in Excel workbooks. I have gradually evolved a system such that these workbooks have become compendia of my

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.

Hi Adrian, dat=data.frame(matrix(0,3,3)) write.xlsx(dat,"z:/dat.xlsx",sheetName="sheet1",append=F) write.xlsx(dat,"z:/dat.xlsx",sheetName="sheet2",append=F) The above code works and creates new worksheets. But if I want to append to an existing worksheet I seem to get an error.

I'd like to be able to read multiple sheets from an excel workbook and use the sheet name to name the resulting dataframe using RODBC. at the moment i've figured out how to do it the long way (see below) but feel sure that there is a speedier & possibly automatic way to do it in R. i've tried to run a loop using sqlTables but it seemed to break the connection. unless i've

Dear all, I would like to import a range of cells (e.g. F10:K234) from an Excel worksheet to R. I have looked for documentation on RODBC and RDCOMClient but I was not able to find enough information to solve my problem and all the examples I have seen were dealing with an entire worksheet, not a range of cells.
