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

Hello I am using Duncan Lang's RDCOM Client package (available on omegahat.org) under R 1.7.0 and Windows XP Pro. Is this the right forum for questions about this package? In case it is, here is my question: Instances of COM objects do not seem to terminate as expected, but leave residual processes running. For example, if I try the simple example: E <-

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'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

Hi Is there a way to specify the location on the screen where a new graphics device opens, for example with a call to win.graph()? I'm using R 1.7.0 on Windows XP. Thank you. Regards, David

Not really an R question but I'm hoping someone can help me out. I'm having problems with the R help page "The R language" and Mozilla 1.3 with the Java 2 runtime environment 1.4.1_02 under Windows XP. The problems occur on the "Search Engine & Keywords" page. I can open two links, but after that links aren't recognized. The problem seems to be javascript

Hi R users, I have been trying to install and use RMySQL on Windows98 for MySQL3.23.55-max using the pulldown menu. I am getting the following errors.

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)
