similar to: Feature request: txtProgressBar with ability to write to arbitrary stream

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 <-

Hi, I am running R 2.12.0 (windows). example(txtProgressBar) gives me some funny screen output with all kinds of special characters appearing and disappearing. It's happening on two different mashines since vs. 2.12.0. Is this a known issue?

Dear R users, I am curious if someone could direct me towards websites/tutorials for uses of progress bars (especially) in R. I can't seem to figure them out. Thanks very much, Scott [[alternative HTML version deleted]]

Dear list members, I have defined a binary operator %append% with methods for some S4 classes. In my documentation file, I want to list the methods explicitly by using e.g.: \S4method{\%append\%}{RecLinkData,RecLinkData}(x, y) In the HTML documentation this comes out right as ## S4 method for signature 'RecLinkResult,RecLinkResult' x %append% y , but R CMD check

Dear R-devel members, I would like to compile a package with two seperate shared libraries. For example, in a package 'foo', a file 'bar.so' built from a distinct set of source files should be installed in addition to the default 'foo.so' (or .dll on windows). Does anyone know about a way to achieve this without having a custom Makefile, e.g. via 'Makevars'?

Hi all, I have a function which makes use of missing() to determine which arguments are provided in the call - basically, there are two sets of arguments that map to different strategies the function uses to fulfill its task. After conversion to an S4 generic I've run into the problem that if a method uses extra arguments that are not in the signature of the generic, usage of missing()

Hi all, I just stumbled across the difference between explicit and 'automatic' row names for data frames. Is there a quick way to find out if a data frame has automatic row names or not? Of course I know this for data frames that I create myself, but what if a function needs to extract this information for an argument? The following example shows that this property is not easily

Hi all, I am posting this again because I got no reply on r-help. Maybe the devel-list is the right place for this kind of question. I've run into the following problem with Sweave: I frequently run Sweave from a xterm console within an X session owned by a different user, i.e. my colleague is logged in on this computer and I do "su" with my username and start R and Sweave

Dear all, I am searching for a possibility to view large data sets (e.g. stored in ffdf objects) in a GUI window in a memory-efficient way. So far I looked at gtkDfEdit (package RGtk2Extras) and gdf (package gWidgets). Both operate (as far as I can see) on data frames stored in memory. gtkDfEdit accepts an ff data frame as input, but there is a long delay before it shows up, so I presume the

Hi all, I've run into the following problem with Sweave: I frequently run Sweave from a xterm console within an X session owned by a different user, i.e. my colleague is logged in on this computer and I do "su" with my username and start R and Sweave afterwards. Now, when Sweave comes to a figure chunk, it sees that there is an X server running and tries to show whatever I plot

Hello all, I posted the following bug last week: # These calls work correctly: match(c("A", "B", "C"), c("A","C"), incomparables=NA) # okay match(c("A", "B", "C"), "A") # okay match("A", c("A", "B"), incomparables=NA) # okay # This one causes R to hang: match(c("A",

Hi all, I stumbled across the following, in my opinion surprising, behaviour of read.table: > data <- read.table(stdin(), sep=",") 0: 1, 2, 3 # Some comment 1: > sapply(data, class) V1 V2 V3 "integer" "integer" "numeric" I was surprised to find that V3 has class "numeric" despite its apparent integer value. I

It's been a while since this thread appeared, but I had the same problem and don't want to keep the solution for myself.

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 --

Buenas tardes: ¿Cuál es el modo más adecuado de incorporar una barra de progreso en la ventana de comandos?. Es para acompañar a un proceso de lectura de ficheros de datos... Necesitaba que la solución fuese multiplataforma. Gracias. Un saludo. Eva [[alternative HTML version deleted]]

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

Hello to everybody I have vector of drug dosage in string format 1.5 mg , 50 mg , 100 mg , 0.5 mg ... The task is to remove last free symbols: ' mg' Any suggestions are highly appreciated

I am reading several hundred files. Anywhere from 50k-400k in size. It appears that when I read these files with R 2.15.1 the process will hang or seg fault on the scan() call. This does not happen on R 2.14.1. This is happening on the precise build of Ubuntu. I have included everything, but the issue appears to be when performing the scan in the method parseTickData. Below is the

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() >
