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]]

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]]

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.

Hello, thanks for bringing this topic up, and it would be excellent if we could come of with a generic solution for this in base R. It is one of the top frequently asked questions and requested features in parallel processing, but also in sequential processing. We have also seen lots of variants on how to attack the problem of reporting on progress when running in parallel. As the author
