Hello, 1. The Situation : ------------------------ The stack traceback is not available when error ouccured in a try(....) -- test.R -------------------------------- f<-function(a){ return ( log(a) ) } try(f("A")) traceback() ------------------------------------------- I get the following message : > try(f("A")) Error in log(x) : Non-numeric argument to mathematical

Hello, all, I'm running Version 1.1.0 (June 15, 2000), on Mandrake 6.1 Linux. I think that I'm getting nonsense results from the density function. When I feed it a sample generated by v<-runif(1000,0,1), I get back some small negative numbers for density values, as follows: >v<-runif(1000,0,1) > dump("v","/home/tomlinso/auction/test.vector.R") >

Dear all, I want to download webpage from a large number of webpage.

Hi, folks! I'm trying to pull in data using read.csv("my URL goes here"), and it really works fantastically. Amazing to pull in live data right off the internet, into RAM, and get busy... however... occasionally there is a server problem, or the data are not up yet, and instead of pushing through a nice CSV file, the server sends a 404 "Not Found" page... Since the

Hello, is it possible to connect a Nortel i2004, (i2002) IP Phone to an * PBX? I have seen on the net that there should be an SIP firmware aviable for the phone, anyone an idea where to get it? Because orginally they use a own protocol to connect to an Meridian, BCM or CSE1K. Another idea is to write a module for * that can handle this protocol. bye SLiME

Hi, I'm trying to implement an abort() method that works just like stop() but does not signal the condition such that try() and tryCatch(..., condition=...) are, contrary to stop(), effectively non-working with abort() calls. In order to achieve this, I stumbled upon invokeRestart("abort"), cf. help("invokeRestart", package="base") that reads "Restarts are

I'm confused by the page documenting tryCatch and friends. I think it describes 3 separate mechanisms: tryCatch (in which control returns to the invoking tryCatch), withCallHandlers (in which control goes up to the calling handler/s but then continues from the point at which signalCondition() was invoked), and withRestarts (I can't tell where control ends up). For tryCatch the docs say

I've disabled account creation for the time being on this forum. I've had a fun weeked of dealing with the slime of humanity banning accounts and deleting posts. But, to no avail. These people don't give up. They don't care about the sites they ruin, or the sysadmins they tick off. I need some volunteers to help moderate and watch the account queue. I'm not going to be the one

Hello, I would like to establish top level condition handlers and restarts, so that I don't explicit calls to withCallingHandlers and withRestarts in many places: For example : > customError function( message ){ err <- simpleError( message ) class( err ) <- c( "customError", class( err) ) err } > withCallingHandlers( { signalCondition(customError(

Dear R-users, I have a question regarding the withRestarts function in R. I´m running a simulation code in which I analyse data using both lme and R2WinBUGS. Now, I want to run this code for 1000 replications, however the model I´m using is a little ´sensitive´, so sometimes the WinBUGS analysis crashes. In that case I want the code to ignore the current results, and redo all steps. This means

I am extending a DBI connection by setClass("TSPostgreSQLConnection", contains=c("PostgreSQLConnection","TSdbOptions")) but the first time I use this I am getting a warning when it tries to coerce the TSPostgreSQLConnection to a PostgreSQLConnection. After the first use the warning stops, but the first warning is causing me problems when I do automatic checks

Hello, I am fairly new to using R and am trying to install it on my Linux machine, running Scientific Linux. I get through running 'configure' and 'make' OK, but when I run 'make check', I get the following error: make check make[1]: Entering directory `/home/gruchti/Programs/R-2.7.0/tests' make[2]: Entering directory `/home/gruchti/Programs/R-2.7.0/tests'

Hej, well I'm not sure because those file that are corrupt have been around for a quite long time. It could have been k3b but I'm really not sure. Right now I was ripping with Audex and tagging with Audex/Amarok/kid3. Those files seem to be fine though. My lates approaches have been with Picard/beets :-) I think it's not possible to share those files without getting in legal

Awesome, this gets the job done. To answer your question: When using C or C++ via Rinside or within a package, those functions do not listen to suppressMessages, e.g. `Rprintf` keeps printing to the console. Since it's common to use wrapper functions in R anyway, they can run `are_messages_suppressed` and pass the information on to an explicit `verbose` argument of the C / C++ function.

Hi all, I'm using R to find duplicates in a set of 6 files containing Part Number information. Before applying the intersect method to identify the duplicates I need to normalize the P/Ns. Converting the P/N to uppercase if alphanumerical and applying an 18 char long zero padding if numerical. When I apply the pn_formatting function (see code below) to "Part Number" column of the

Hello to everybody, I just subscribed to this list. I find R a really nice environment for statistical analysis. I started to use it some days ago. I use it at home in my Linux box, but I would like to use it in my institute in my Digital Alpha (my machine runs OSF1 V4.0). I tried to compile the distributed source code, without success due to some errors. And the binary available is in RPM

I am looking for documentation on handling snapshots. The main tasks are: 1. Create a snapshot 2. Roll back a snapshot 3. Merge the snapshot into the base to start the cycle over. Currently I've done steps 1 and 2 into a single qcow2 image. I'm running a relatively old version of libvirtd on CentOS 5, libvirt-0.8.2-29.el5_9.1. Thanks. Bill -- INTERNET: bill at

Hi all, I would like to create a function that detects if suppressMessages has been invoked upon running that same function. I was looking through {https://cran.r-project.org/doc/manuals/r-release/R-ints.html}, but I haven't found an answer. I do not understand **how** suppressMessages works. I have not received an answer on SO
