Hi Does anyone know of any R routines to send emails from R, under Windows? I thought about writing such a facility using the R(D)COM package to drive e.g. MS Outlook, but I don't want to reinvent the wheel. I have found a function Sys.mail in the library syskern, but this only works under Unix by shelling out a mail command. Thanks, David

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 Does anybody know of any R packages under Windows to produce video files from a sequence of R graphs -- e.g. in .wmv or avi format? Thanks David

Hi. I have the following question about reading from large data objects from within R functions; I have tried to simplify my problem as much as possible in what follows. Imagine I have various large data objects sitting in my global environment (call them "data1", "data2", ...). I want to write a function "extract" that extracts some of the rows of a particular

Hi I am using the heatmap function in package mva to look at large correlation matrices visually. Is there any way to "flip" the output of heatmap plot left-right so that, if presented with a correlation matrix, it plots the unity elements in the correlation matrix along a diagonal from top left to bottom right? For example: library(mva) x = matrix(rnorm(1000), ncol=10) z = cor(x)

Hi, I?m using R package RDCOMClient (http://www.omegahat.org/RDCOMClient/) to retrieve data from MS Excel workbook. I?m using the code below to count the number of sheets in the workbook and then loop the data from sheets in to a list. ############# R code ################### library(gdata) library(RDCOMClient) xl <- COMCreate("Excel.Application") sh <-

The example from the help page for strptime has the following oddity: > dates <- c("02/27/92", "02/27/92", "01/14/92", + "02/28/92", "02/01/92") > times <- c("23:03:20", "22:29:56", "01:03:30", + "18:21:03", "16:56:26") > x <-

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();

Hi, I am trying to use the mimR Package. According to its help pages it needs the RDCOMClient package to run. When I try to evaluate a model I get > m.sat<-mim("..",data=gm.dat) Error in mim.cmd("clear; clear output") : couldn't find function "COMCreate" > m2.sat<-emfit(m.sat) Error in toMIM(mim$data) : Object "m.sat" not found >

I am using RDCOM as a data-transfer between R and C#.net. I got a question on datasets with missing data. For instance, if list = c(1,2,3,NA,5), in R, typeof(list) is integer but, in C#, I did not see a suitable data type for (1,2,3,NA,5). Of course, one can use is.na to transfer (1,2,3,NA,5) into string[] in C#. So, how to handle NA in this case? Please help. Thank, -james

I got a table on SQL Server, which has columns EquationId (int) and Formula (varch(900)). I need to select Formula with certain EquationId, for example, Select Formula from OGA_DEV.dbo.Equation where EquationId = 3 I tried to work within RGui using RODBC: > library(RODBC) > conn = odbcConnect("SQL Server") > odbcQuery(conn, "Select Formula from OGA_DEV.dbo.Equation where

Hi I'm having problems getting the "factorized" argument in solve.QP (part of the quadprog library) to work as expected. The helpfile states that when the factorized argument is set to TRUE, then the function requires the inverse of a square-root factor of the Hessian instead of the Hessian itself. That is, when factorized=TRUE, the Dmat argument should be a matrix R^(-1), such

Hi I am using package RODBC version 1.0-1 under R version 1.7.1 on Windows XP Pro. I am having problems writing a new table to an (Excel) database using sqlSave. I connect to an empty Excel spreadsheet using odbcConnectExcel (which, I believe, uses the Microsoft Excel Driver DSN). Then I try and save a new table to the database(spreadsheet) using SqlSave, but obtain an error message. Below is

Hi Does anyone know of any automatic way of mapping out the dependencies of a function -- i.e. automatically listing which other functions that function calls? I tried using all.names or all.vars, but I can't get it to work on a function: e.g. > test = function(x, y) return(sin(x + y)*cos(x + y)) > all.names(expression(test)) [1] "test" I guess the problem is that all.names
