Dear All, I am using excel.link package to open and modify Excel files. When I manually open Excel, all my add-ins are loaded without a problem. But when I open Excel using excel.link package, like: xls<-xl.get.excel() xl.workbook.open("MyFile.xlsx") some Excel add-ins are (installed but) not loaded. Since the problem is related to local add-ins at my side, I cannot reproduce the

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

Hello. I am using some dates I read in excel in R. I know the excel origin is supposed to be 1900-1-1. But when I used as.Date with origin=1900-1-1 the dates that R reported me where two days ahead than the ones I read from Excel. I noticed that when I did in R the following: > as.Date("2011-3-4")-as.Date("1900-1-1") Time difference of 40604 days but if I do the same

Even using the VBA back of Excel to create interfaces with R would make a lot of sense. Suppose I could have access to VBA macros that import and export data into R , it would be great. The R GUI series like Rattle come even closer to Excel...so a VBA _R_ExCel package might be useful to ordinary folks . Besides Excel costs money, so adding R functions to Open Office would help both of them ( if

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

What is the equivalent for formatted tabular output of the various very sophisticated plotting tools in R (plot, lattice, ggplot2)? In particular, I'd like to be able to produce formatted Excel spreadsheets (using color, fonts, borders, etc. -- probably via Excel XML) and formatted HTML tables (ideally through a format-independent interface), and preview them using commands within R, just as

Hi Experts, I was trying to write a data frame which has a header row, from R to Excel disk file using RODBC ( RODBC_1.3-1) package. I met with an issue:- If in sqlSave(), I set a parameter "colnames=FALSE" then I get first row as header in excel file. If 'colnames=TRUE' then it gives me first 2 rows as header in excel file. Actually, according to my

Hi list, Despite the question I asked last time (I will re-install the FC3 with Samba 3.0.14a on another computer for replacement soon), I still have one more question on Excel files. I found that Excel file opening is extremely slow (especially on slow connections, i.e. VPN). The case is really bad, it takes around 2 mins to open a excel file of around 400k. Actually we got both side having

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.

Dear group, I am working on a rather big project where the output data frames have dimensions of 3000 x 15 or greater. We are using xlsx and xlsx2 to write the data.frames to Excel sheets. Since recently we get the following error, when trying to write the data frames to the excel sheets: Error in ls(envir = envir, all.names = private) : invalid 'envir' argument We figured out that

Y muchas veces, se guardan los datos en esas hojas excel, donde los usuarios, que no son estadísticos, que no conocen R y no lo van a conocer completan esos excel. Es más cómodo hacer que guarden los datos en esos ficheros fijos respetando ciertas reglas en cuanto a formatos, estando dichos ficheros en ubicaciones fijas y llamar los datos desde R directamente a los archivos en sí, que tener que

Dear all, I am interested in reading Excel spreadsheets (*.xls) directly into R (I am using version 1.1.1 at the moment). I have not had much luck so far. For the time being, I have been converting Excel files to comma delimited files (*.csv) and reading these into R (using commands such as "read.csv"). This works well, but it would be more efficient if I could read the Excel files

Hello all, I have always experienced VERY SLOW response times on opening an EXCEL sheet ever since I had started to use SAMBA WAY back. I have been hoping that a newer release would fix this one issue but it never seems to happen. Does anyone know what could be the problem? I can open the same Excel sheet on a Novell server and it opens instantly. I have no problems with WORD documents. They
