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

Hi, This may be due to several reasons. That I can think about: 1) Ensure you close *all* possibly open workbooks: nBooks <- xl[["Workbooks"]]$Count(); for (i in seq_len(nBooks)) xl[["Workbooks"]]$item(i)$Close(SaveChanges=FALSE); 2) The excel application reference does not seem to be really released until the garbage collector runs. So this may help: xl$Quit();

Hi, I?m using R package RDCOMClient (http://www.omegahat.org/RDCOMClient/) to retrieve data from MS Excel workbook. I?m using the code below to count the number of sheets in the workbook and then loop the data from sheets in to a list. ############# R code ################### library(gdata) library(RDCOMClient) xl <- COMCreate("Excel.Application") sh <-

Hi all, I have been hunting around for hours trying to figure out how to generate a stacked line chart using ggplot2. This type of chart can be generated in excel 2007 by selecting: Chart type > Line > Stacked line. I can generate a stacked area chart using the following code: p <- ggplot2(~, aes(x = ~, y = ~, colour = Type)) + geom_area(aes(position = 'stack', fill = Type))

Hi sorry if this is really basic but I am just starting on R. Can anyone point me at how to write R objects into Excel 2007 files. I have seen how to set up a connection to a file through odbcConnectExcel2007(xls.file, readOnly = FALSE, ...) but it doesn't say anything on how to write data Thanks _____________________________________________________________________ The

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

Hi all, I have a question about setting arbitrary breaks/labels when using GGPLOT and date/time data on the x-axis. I want to specify the breaks/limits arbitrarily rather than using scale_x_date(major = 'blah'), much like when arbitrarily defining breaks/labels using scale_x_discrete(breaks = blah, labels = blah) I have tried variants such as: scale_x_date(major = seq(from =

Hi, I am trying to connect to an Excel2010 file while another user is entering data. (Obviously it would be better to set up a SQL database, but this is not an option at this point.). Typically we are not working on the same sheets. However, if possible I like to read the most current excel file into R. RODBC works great as long as the other user has not open the file. I tried: channel <-

I have recently installed MS Office 2007 in Wine 1.2 on Ubuntu 10.04 64-bit I have noticed that I cannot switch between two excel workbooks. I can either work on only one excel at a time or do a lot of jugglery to switch between the two. It will be great if anyone can give me a solution as I need to work on multiple excels most of the time. Thanks Prasad

I tried creating a .xlsx file using odbcConnectExcel2007 and adding a worksheet with sqlSave. This seems to work, I am even able to query the worksheet, but when I try opening the file in Excel I get the following message: "Excel cannot open the file 'test.xlx' because the file format or file extension is not valid. Verify that the file has not been corrupted and that the file

Dear all, I need to download an excel file from net, on which I have address like http://www.2shared.com/file/MMSMWv4B/MyData.html. Can I somehow directly download this file into my R workbook? Thanks, [[alternative HTML version deleted]]

I have probably an old question. I have R.3.0.1 installed in 64 bit windows 7. The odbcConnectExcel in RODBC library does not work. Tried odbcConnectExcel2007 still does not work. Any ideas.

I'm running XLConnect 0.2-1 that depends on rJava 0.9-3.

Apologies if this is already answered elsewhere, but I could not find the answer searching the archives. I am trying to bring my data in from an .xlsx file. The data of interest is an n x m array, but it is preceded with ~2 columns and 30 rows of instrumental "information." An abbreviated example (cols denoted with "," for this example: Subject , 01 wavelength, 400 (30

Hello, I just discovered that I cannot close the Excel application and task manager shows numerous copies of Excel.exe I tried both x$Quit() # shown in the rcom archive and x$Exit() and Excel refuses to die. Thank you very much. S. "You can't kill me, I will not die" Mojo Nixon I also have a problem with saving. It produces a pop-up dialog and does not take my second

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, This is a little off-topic, but it is on the general topic of getting data in R. I'm looking for a excel macro / vba script that will export all spreadsheets in a directory (with one file per tab) into csv. Does anyone have anything like this? Thanks, Hadley -- http://had.co.nz/

Hi, i'm trying to read some data from excel files but it seems that neither xlsReadWrite nor sqlFetch (RODBC) doesn't like the format (Excel 5.0). When i open the file in Excel and save it in a new format Excel 97 -2003 everything works fine. Is it possible to use ODBC connection to open old format files, or i guess i will have to open and save every file in Excel in new format, which

I have been trying to read some data from an Excel workbook without success. The workbook is in .xls format and has multiple sheets, one with the sheet name Data, which is the sheet I wish to read from. One complication is that the header row of this sheet is comprised of dropdown boxes. I tried what I normally would do plus some variations. Here is the output. > require(RODBC) >
