How can I disable the progress bar ?

[statquant]

Hello, is there a way to disable the progress bar , if not would you kindly add an option like options(clustermq.progress = FALSE). I can PR if you point me to it

Have you tried

Q(..., verbose=FALSE)?

?Q states

verbose: Print status messages and progress bar (default: TRUE)

Sorry I should have said that I use foreach

Looks like currently your only option is to suppressMessages(), but we should probably support the .verbose argument in foreach.

Should be as simple as:

--- a/R/foreach.r
+++ b/R/foreach.r
@@ -56,7 +56,8 @@ cmq_foreach = function(obj, expr, envir, data) {
         data$pkgs = unique(c(data$pkgs, obj$packages))
     }

-    result = do.call(Q_rows, c(list(df=args_df, fun=fun), data))
+    result = do.call(Q_rows, c(list(df=args_df, fun=fun, verbose=obj$verbose),
+                               data))

     accum = foreach::makeAccum(it)
     accum(result, tags=seq_along(result))

Applying the suggested patch above will not only print clustermq messages, but also low-level foreach messages.

I'd argue we are not interested in those.

I checked whether I could solve this with:

• Different levels of .verbose, e.g. 1 for clustermq messages and 2 for foreach messages. This does not work, because foreach checks that the type is logical
• By adding an additional .progress parameter to foreach, which does not work because it does not support ...

Hence, if you want to suppress the progress bar, you can still wrap your call in suppressMessages(...).
