similar to: To import data to R from Excel

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. Thanks, Jean-Noel Jean-Noel Candau INRA - Unit? de Recherches Foresti?res

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.

Hello all, I have a business user who generates monthly reports in MS Excel in a particular format. The data I need is present in different portions of this excel file. Is there a way to read different cells from a particular excel worksheet? i.e., cells b50:d100 in the Inputs worksheet. I am investigating odbcConnectExcel but did not yet see such capability. Appreciate your help. Jeevan

Hello, Thanks in advance for reading. I''m attempting to export data to an excel spreadsheet, and have done so successfully using RubySpreadsheet ( http://sourceforge.net/projects/rubyspreadsheet/ ) which is a port of the Perl WriteExcel module... Many of the methods however were left out, one of them being "insert_bitmap" and unfortunatley the bitmap is an important part

Dear all I use ggplot2 extensively for my plotting routines and rexcel to have the best of two worlds. (RExcel v 1.75 and R (D)Com v. 2.5) I can run my ggplot functions, such as qplot(...), in scratchpad mode, but not in Macro nor Worksheet functions mode. I have tried the following in Macro mode: Call RInterface.RRun("library(ggplot2)") ... Call

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

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.

As part of my project to put different types of results into worksheets, I would like to be able to put an auto-generated methods section. If I compose in RWinEdt, read into R, and use write.table with a .txt file extension, what I get out has line-breaks that correspond to those I put in in the first place. If I do the same thing but write.xls with .xls extention, I get an Excel worksheet

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/

All, Relatively new R user so this is probably an easy question to answer. I am able to generate a cluster for my dataset using hclust() then ploting the data with plot(). This results in an image with a dendrogram with my sample names along the bottom. Great! However, I now need a way to get that sample order from the image into excel. i.e. sample 7 was on the far left, sample 19 was in

Hello! I have no problem reading Excel files (each worksheet in the file is a "table" which can be read - at least in my case). What I would like to do is to read such a table, change it (just the contents, not the format) and write it back, and this I can not do. I am getting the following error messages (3 slightly different attempts): > sqlSave(con, x, tablename =

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

I gather from reading the back-issues of r-help that it should be possible (modulo a number of caveats) to read an excel (yuck!) file into R using RODBC. I have obtained and installed ODBC and the RODBC package, but cannot for the life of me figure out how to go about it. Can anyone give me a simple recipe? I have an excel file on cdrom, say: /mnt/cdrom/melvin.xls I have started R and loaded
