getWinProgressBar does not return previous value
I am trying to use winProgressBar, however I find that although setWinProgressBar updates the value on the screen, getWinProgressBar does not return this value. E.g > pb <- winProgressBar() > setWinProgressBar(pb, 0.2) > getWinProgressBar(pb) [1] 0 I tried the same with tkProgressBar, and it is working as I would expect from the documentation. > pb <- tkProgressBar() >

A question about "txtProgressBar" function
Hi, I tried to add a progress bar to my script, but it seems the "txtProgressBar" function will wipe out what I want to print before it(for example - the "Hello" in following script), and the parameters "title" and "label" do not work either. How can I put a title for the progress bar? or is there any other better function I can use? testit <-

Feature request: txtProgressBar with ability to write to arbitrary stream
Hi all, I use txtProgressBar to monitor progress of large computations. What I miss is the ability to redirect the progress bar to a stream other than stdout, specifically to the message stream. This would be useful for running Sweave scripts: When redirected to stderr, the bar could be visible even though console output is diverted to the output file (and there would be no cluttering of the

Cross-platform function availability
Hi all, Is there any way to determine which functions are available on which platforms? For example, winProgr essBar (and related functions) are only available on Windows, but what about tkProgressBar and txtProgressBar? Is there any way to figure out which functions are only available on certain platforms, without installing R on that platform and checking? Thanks, Hadley --

Procesos paralelos
Hola: Vuelvo a la carga con algo que resolví hace años y que ahora me ha dejado de funcionar y no consigo arreglar. A ver si alguien me sugiere algún enfoque o directamente la solucion. Utilizo R en muchos procesos ETL y la cuestión es que me encuentro con que tengo que hacer inserts en un BBDD de SQL Server de varios miles (a veces millones de registros) que mientras R las realiza parece que

How to stop buffering of "cat"
Hi All, My R code takes very long time to finish the processing. I want to see at what stage the script is running. So I wrote some output messages using cat. But instead of displaying the cat messages at different stages they are buffered and displayed in the end when entire processing is done. Can you please suggest how to stop this buffering or some alternative way to display messages Thank

Hola, ¿qué tal? Si la base de datos de destino es SQL Server, ¿por qué no pruebas con la función dbBulkCopy del paquete https://github.com/agstudy/rsqlserver? Debería poder cargar millones de registros en segundos. Al menos, en una única transacción en lugar de múltiples como con sqlSave. Un saludo, Carlos J.

Population pyramids
Hi, I hope somebody can help me with this issue: I am doing population pyramids using the barplot command, so in the left side I have male age structure and in the right side the female age structure. To plot the male age structure I put the data in negative numbers. Now, I want to change the sign in the bar plot in such way that I have no-sign numbers, both in left and right side of the graph. I

Labels on a pyramide
I am using pyramid.plot() from the plotrix package. I have something like this ############################################ xy.pop<-dados$masfr xx.pop<-dados$femfr #agelabels<-dados$femlab xycol<-color.gradient(c(0,0,0.5,1),c(0,0,0.5,1),c(1,1,0.5,1),11) xxcol<-color.gradient(c(1,1,0.5,1),c(0.5,0.5,0.5,1),c(0.5,0.5,0.5,1),11) xylab<-dados$maslab xxlab<-dados$femlab

pyramid.plot in plotrix, axis labelling
Hi, I've been looking at ways to make pyramid plots in R. I like the pyramid.plot method in plotrix as it seems the simplest to use and building them in ggplot looks a bit more code intensive than I'd like, being as I'm new to R. This package does pretty much what I need it to do, however I can't seem to scale the x axis labels. The other labels scale fine with labelcex. I

R crashes when setWinProgressBar is give a numeric value for label argument
This problem can be seen by the following commands: > pb <- winProgressBar(max=1000, label='0') > b <- 1 > setWinProgressBar(pb, b, label=b) This set of commands (on windows of course, XP in this case) causes R to crash. This is not strictly a bug since the documentation states that the label argument should be a character string and using as.character(b) does work

Gracias, Daniel!. No veo claro cómo adaptarlo (en mi caso se trata de un apply de tal modo que para cada item de la lista leo el fichero de datos cuyo nombre se indica, y en total leo tantos ficheros como elementos hay en la lista). Le daré una vuelta a ver si consigo aplicarlo bien y si no en tal caso os consulto. Saluditos! Eva ________________________________ De: daniel

Confused with an error message related to "plotrix" library in the newer versions of R.
Dear R Users, Greetings! I am confused with an error message related to "plotrix" library in the newer versions of R. I used to run an R script without fail in the earlier versions (R 2.8.1) of R; but the same script is now throwing up an error message in the newer versions (Now I have R 2.13.0 & R 2.14.0). Herewith I am furnishing the same code for your perusal. It would

Router for SOHO network - hardware considerations
Hi, Last week I finished installing a small network in a private school : one server (an old IBM X225), seventeen desktops (Fujitsu Siemens PIV 2.4 GHZ, 512 MB RAM, 40 GB HD), all running CentOS 5.5. One extra machine is acting as a router, in that it is installed between the DSL modem and the network, with two Ethernet cards, and it's taking care of DHCP, DNS, NTP and also acts like a

Adding textbox to multiple panels in lattice
Dear R-users, I am trying to add some text in a textbox to all panels in the following example file. Using the panel-function, I can add a white rectangle with panel.rect but then I have to fit in the text into the box by hand and it will not automatically be centered. Does anyone know how to add the text centered with a white box around it automatically? Is there something like panel.textbox for
