Dear R users, I've just posted a similar question about Illustrator. This time I would like to export the results of my statistic tables and my dataframes into Excel files. Up to now I've used write.csv(), but I have to resave every file in .xls in Excel. I would like to know if there is a function or package to export directly into *.xls. I have found xlsReadWrite which would be

Dear R-experts, It is a quite stupid question but please help me. I am very confuced. I am able to import normal txt ant mat-files to R but unable to import .xls-file I do not understand the online help. Can please anyone send me the corresponding command lines? The .xls-file is attached. In my file we use commas for the decimal format (example: 0,712), changes might be needed. Thanks, Corinna

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 am reading dates in Excel2007 into R. Here are the functions I used: library(RODBC) channel<-odbcConnectExcel2007("myfile.xlsx") tmp<-sqlFetch(channel,"1",as.is=T) The dates in myfile.xlsx are all in this format: mm/dd/yyyy. But when I read it to R, some columns look like "yyyy-mm-dd 00:00:00", some columns look like "yyyy-mm-dd", and some

Hola a todos, Mi nombre es Juanjo. Llevo un tiempo intentado hacer funcionar un programa que necesita de la instalación de RPROJECT y REXCEL. He mirado varias guías e instalado los programas pero obtengo varios errores. El principal es que tras instalar RProject, Rexcel y statcon y al intentar correr esta macro desde Visual Basic… Sub Start() RInterface.StartRServer

A common process when data is obtained in an Excel spreadsheet is to save the spreadsheet as a .csv file then read it into R. Experienced users might have learned to be wary of dates (as I have) but possibly have not experienced what just happened to me. I thought I might just share it with r-help as a cautionary tale. I received an Excel file giving patient details. Each patient had an ID

Hello, I just installed RExcel but I have some problems. I am writing you the set of commands that I used: > install.packages("RExcelInstaller", "rcom", "rsproxy") > library(rcom) > comRegisterRegistry() > library(RExcelInstaller) > installstatconnDCOM() > installRExcel() But when I select RStart from add-ins I see this written "No R server

Hi community. I'm fairly new to R and have a basic question. When I try to install RExcel with the code: install.packages("RExcelInstaller", "rcom", "rsproxy") I get the message below: Warning in install.packages("RExcelInstaller", "rcom", "rsproxy") : 'lib = "rcom"' is not writable Error in

Dear all, does anyone know if it is possible to connect a Windows RExcel instance to a linux R instance? Within Rexcel, I find the option "Remote Server Address", but I wonder what the installation procedure on my linux (ubuntu) R looks like (if possible at all)? Thanks Philipp

Hi, I'm using R-2.8.1 for windows. I wrote a script calls the RODBC package to run sql queries against an oracle database. It runs fine when run from the rconsole and returns a data.frame with a summary for a set of experiments. I want to run this script using the rinterface.RunRFile command in an excel plugin, using the rexcel package. When I run the code from my excel plugin I

hello all i have a quick question. i have been using the RODBC library (trying to read Excel data into R but i am doing this by using Rexcel. this is probably not the correct forum - sorry for this). my code is shown below: Sub A() 'start the connection to R Call RInterface.StartRServer RInterface.RRun "library(RODBC)" RInterface.RRun "A =

Hi, I was trying to run your code in my VBA editor, however could not succeed. The execution stumbled in the line "Call Rinterface.StartRServer" itself. I have RCOM package installed into my R environment. Do I need to install anything else to run that? Would guys here guide me?

Estimados: Tengo un directorio con varios archivos Excel quiero importarlos todos y grabarlos en un único archivo .dbf.

Hello: First, RExcel completely rocks! Hat tip to the development team. However, I don't understand something very basic about it. Suppose I put the following code in two cells and choose the Run Code option plot(runif(20),runif(20)) text(.5,.5,"Hello") I get the expected plot. HOWEVER, if I put the following in a cell and hit Run Code, I get nothing. runif(20) HOWEVER, If I

Hi, I am installing Excel using package "RExcelInstaller". When I tried to run installRExcel() I got this error message: You don not have the R package rcom installed. The (D)COM server installed which will aloow you to use the background server in RExcel. Since rcom is not installed, foreground mode will be unavailable. You may continue with the installation, but in most

I have used xlsReadWrite to read data from an Excel spreadsheet. I had a problem with converting times of the day so that I could create POSIXct date-time objects. I was wondering if there was a better solution. Excel stores times of the day as fractions of a day so I wrote a function to convert the fraction to a number of seconds, extract the hours, minutes and seconds and output it in ISO
