Folks, Is there a parameter somewhere in RODBC that enables more columns to be retrieved from an Excel worksheet? # This next bit uses an undocumented call in RODBC z <- odbcConnectExcel("./BBaselinePtQaires_apr2011.xls") BQ <- sqlFetch(z, "BBaselinePtQaires") Gives me: z RODBC[1] And BQ 134 obs. of 59 variables I have all the rows in the worksheet but only the

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?" Is there somwhere a manual about this package with good examples? I've read the Package description... but there are not really good

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.

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.

I would like to open OpenOffice (LibreOffice) .ods files in R. I've tried the ROpenOffice package from omegahat, but unfortunately, the read.ods() function attempts to use the values of the first column in a worksheet as row names, and thus does not allow duplicates in there (which, even more unfortunately, occur in my files). Also, the function does not allow to forward any other

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

Dear R-users, I have to read data from a worksheet that is available on the Internet. I have been doing this by copying the worksheet from the browser. But I would like to be able to copy the data automatically using the url command. But when using "url" command the result is the source code, I mean, a html code. I see that the data I need is in the source code but before thinking

Hi, I would like to some excel files with some worksheets. I tried this with the following R script: library(gdata) i<-1 rc<-0 while(rc != "try-error") { wksh<-try(read.xls("cluster-microarray-FW.xls",sheet=i,verbose=TRUE,perl="perl")) rc<-class(wksh) print(sprintf("------- i=%2d rc=%s ---------------",i,rc)) if (rc !=

I can currently append an entire worksheet with write.xls, but would also like to be able to append within the same worksheet. Is this possible? It doesn't seem to work if I use append = T Thanks, Mark -- Mark W. Kimpel MD Neuroinformatics Department of Psychiatry Indiana University School of Medicine

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

Hi list, Is there a R function I can use to extract the worksheet names from an Excel file?? If no, any other automatic ways (not using R) to do this? thanks! ...Tao

Hi, If I open up a worksheet in MS Excel 97, the file name is modified by appending an extra .xls to the name. Multiple .xls's are possible, and it is not necessary to save the worksheet. I'm running Wine-20010305 compiled on a SuSE 7.0 running a stock 2.4.2 Linux kernel. MS Excel is being run from an existing Win98 system partition. Thought someone might want to know, Dick --

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.

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

Hello, my question is rails related though it is also somewhat specific to the prawnto plugin (installed latest version as of 2010-03-15). I would ask on a prawnto forum/list if I knew where one was. Anyhow, I''m using rails 2.3.5 (with ruby 1.8.6 patchlevel 111) in an app that is successfully using the prawnto gem (with the prawn gem version 0.7.1). I''ve got a a

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

Okay, so my issue isn't really a technical one but more of needing advice on the best way to program this. I have a user in Colorado who works from home but frequents our office in Colorado.

Hello, the sqlSave function is used in order to write a dataframe on excel. This function creates worksheets using the attribute tablename and writes the data.frame in it. What I want to do is to create this data.frame but being able in case this worksheet already exists to delete the former datas and write the new ones in it. I used the safer and append attributes.
