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.

Hi, I'm trying to read several Excel sheets from an Excel file into a list. I'm using read.xls from package 'gdata'. I would like to know how I can check the number of sheets before the loop (in the example below) so that I could adjust the loop counter? Any suggestions? DF.list <- list() for (i in 1:4) { DF.list[[i]] <- read.xls("sample_file.xls", sheet=i,

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();

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

Dear R experts, I am trying to import some data from some Excle files into R. My Excle file contains about 50 sheets. One solution I can think about is to convert my Excle file into csv file first and then load data into R using 'read.csv'. But it seems to me that 'read.csv' only supports reading one sheet (or 'one file') each time, so that seems I have to create 50 csv

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.

Hallo all, I`ve read a lot of things in this forum about an Excel export via R.

Hi, I would like to some excel files with some worksheets.

Dear Listers: I have a couple of data frames to report and each corresponds to different condtions, e.g. conditions=c(10, 15, 20, 25).
