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? testi...

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? Best, Jalla -- View this message in context: http://r.789695.n4.nabble.com/txtProgressBar-strange-behavior-i...

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 i...

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]]

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 -- http://had.co.nz/

...Bar() > 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() > setTkProgressBar(pb, 0.5) > getTkProgressBar(pb) [1] 0.5 ... and I get the same result using txtProgressBar . Does anyone using winProgressBar find the same behaviour, or know the reason for it?

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]]

Hi All, I am trying to build in a progress-tracker into my loops that let me have a sense of their progress. I'd like to be able to output to screen a series of periods "...." etc. for each completion of the loop, but I <don't> want to build a pyramid, e.g. . .. ... .... etc. So I need to be able to delete <the last line> of the console entry to accomplish this.

Dear All, We are currently working with very large datasets which even in R require a lot of calculation time. Is there an option of including a function/ tool or something alike which shows the remaining time of calculation? Just to see whether there is any progress or whether anything has crashed and to get a feeling whether we have to wait for 5 min or 30min... Any help is greatly

Hello all, I am using Rprintf in a C for loop (from .Call) to print a progress indicator showing the current percent complete. The loop I am doing is an time intensive call to another function. I have noticed that Rprintf does not print to the R-window until the entire loop has been completed. When it reaches the end of the loop it suddenly prints 0 percent to 100 percent in a split second.
