Hi Is there a way to programmatically tell whether R is running in batch or GUI mode?

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 want to do simulations with an external simulation model. For this purpose I wrote a R-script which makes the pre- and post-processing of the data (generate scenarios, analyze results). The R-script writes the input file for the simulation with e.g. write(x, file="test.dat", ncolumns=10) The problem is, however, that this command (and even constructions with cat) will add a

I have a problem, that the plot of mathematical formula sometimes crashes R on Linux (SuSE 6.2 and 7.0 on a Dual PIII/500 machine with 1GB RAM). The problem occurs for example in demo("graphics"), i.e. in the last part were the mathematical symbols are plotted. There are several circumstances to reproduce this segmentation fault, but the following is one of the most simple examples. The

Hi, I am almost new to R. Would any one show me (please include an example) how to clip a contour or image figure so that I only see the image or lines inside a selected area?

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 need 'rw1062.zip' since i can't get excel, R1070 or R1071 to work with the R (D)COM Server everything worked fine in the god rw1062 days the lapack routines can't be loaded 'unable to load shared library c:\r/moduleslapack.dll, the specified library could not be found' don't know if it's the forward slashes that anoys windows btw, the libraries are in the

Hi - I am getting different results when I run the numerical integrator function lsoda (odesolve package) on a Mac and a PC. I am trying to simulating a system of 10 ODE's with two exogenous pulsed inputs to the system, and have had reasonably good success with many model parameter sets. Under some parameter sets, however, the simulations fail on the Mac (see error message below). The

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)

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 all, I think this question could be quite trivial, but I can?t find out the solution... How can you compute the statistic "mode" of a sample, in case it exists (as mode() returns the mode of an object)? I tried help.search("mode") but I couldn't find a clue... Any help would be much appreciated. Regards, Aurora

hi all i have another probably simple question. I have three variables say x, y and z. x and y are quite large and z is relative small. how can one plot the three variables on the same graph with two separate axis? (one for x and y and the other for z) e.g. x<-c(101,110,150,167,120) y<-c(120,135,175,95,200) z<-c(0.001, 0.15, 0.6, 0.8, 1) regards Allan

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

Dear R developers, I've got an information from Prof. Ripley regarding a bug found with AdressSanitizer in one of our packages. It is now fixed, thank you for this information. Now, I would like to run AddressSanitizer myself before submitting the patched package to CRAN. Is there a recommendation of a suitable Linux distribution with gcc 4.8, ideally an ISO image or (even better) a
