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

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

I am looking for information on experimentation with the use of R in the teaching of statistics and science in schools. Any leads would be very welcome. I am certain that there is such experimentation. I've made this inquiry on r-sig-teaching, with no response. John.

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

Hi list, I used to work with RExcel in excel 2003. Now in 2007, I tried the same RExcel, but it did not work. I got R version 12. I downloaded/installed the latest version of RExcel 3.2.0 from http://sunsite.univie.ac.at/rcom/. It has added the RExcel add-ins, but when I click on starting R in add-ins, I get the following sequentional errors: Errors: SCtools not available SCTools can not be

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

Hi,   I would like to make a program that reads excel files, and writes the cells of which contents is not a formula to another file. I don't think this is possible with RODBC, but it may be possible with rcom.     I read the documentation of the rcom package, but I was hoping somebody knows a good web resource for more eleborate info. I tried Googling, but alas (did you know rcom also is a

Hi R-users! I'm trying to create an easy Excel chart using the package RDCOMClient. The following example is working fine: #------------------------------------------------------------------- library(RDCOMClient) xlLocationAsObject <-2 xlXYScatterSmoothNoMarkers <- 73 ex <- COMCreate("Excel.Application") wb <- ex[["Workbooks"]]$Add() sh <-

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

I'm searching for answers to four questions (I've been searching the net for hours...) In Windows XP, is it possible to call R functions from a c program? (I've found examples for Linux/Unix but not Windows) If so, is there a simple example to get started using gcc with R-2.10.0? If so, is it possible to write a simple interface using a c dll to call R functions from a Visual

I have a big contingency table, approximately of size 60*2*500*500, and I need to count the number of cells containing a count of 1 for each of the factors values defining the first dimension. Here is my attempt: tab1<-with(pisa1,table(CNT,GENDER,ISCOF,ISCOM)) tab2<-apply(tab1,1:4,function(x)ifelse(sum(x)==1,1,0)) tab3<-apply(tab2,1,sum) Computing tab2 is very slow. Is there a faster

I'd like to be able to read multiple sheets from an excel workbook and use the sheet name to name the resulting dataframe using RODBC. at the moment i've figured out how to do it the long way (see below) but feel sure that there is a speedier & possibly automatic way to do it in R. i've tried to run a loop using sqlTables but it seemed to break the connection. unless i've

Hi, I am using RExcel both at work and at home and am facing a couple of challenges. The one at home is that when using RExcel and trying to run any code that involves changing the working directory, I get the following error. Error in command: setwd("C:\\Raoul\\R\\R Maps_UK Maps_Test\\NUTS_03M_2006_SH\\shape\\data")\n cannot change working directory The one at office is more

Hi - For a while I've used RExcel without problems to run a repeating portfolio optimization problem where I solve for a portfolio allocation targeting a particular risk, then solve for a different risk, etc. I call the commands with (e.g.) rinterface.Rrun "(R command)" Recently that macro started blowing up, returning #RErrors, and when I try to trace the error I find that it is
