verbose function in nmf()

[grimwoo]

Hi, I wonder if there was any parameter like "verbose = TRUE" to display a progress bar for nmf() procedure. Because it takes 12 hours to run nmf() without any information in R. It would be better if such a verbose parameter could at least tell me that "this code is still running".

.options = "v"

verbose - v: Toggle verbosity (default: FALSE). If TRUE, messages about the configuration and the state of the current run(s) are displayed. The level of verbosity may be specified with an integer value, the greater the level the more messages are displayed. Value FALSE means no messages are displayed, while value TRUE is equivalent to verbosity level 1.
