Suppress ggpairs messages when generating plot

Question

ggpairs prints out a progress bar and estimated remaining time while generating plots, which is nice when used interactively since some of the computations can take a few seconds. But when making documents, like R notebooks, these printed messages end up in the report. ggpairs had a boolean verbose option, but it's depricated now. Is there an alternative? I can't seem to find one.

To see the messages try:

library(GGally) ggpairs(mtcars, columns = c("mpg", "cyl", "hp", "disp", "am", "qsec"))

In a document it ends up including:

plot: [1,1] [==-------------------------------------------] 4% est: 0s

plot: [1,2] [====-----------------------------------------] 8% est: 6s

plot: [1,3] [=====----------------------------------------] 12% est: 5s

plot: [1,4] [=======--------------------------------------] 16% est: 5s

etc

I tried `message = FALSE, warnings = FALSE` but they still show up. — adatum, Jan 10 '17 at 20:11
I also tried wrapping the code in `suppressMessages()`. Didn't work either. — adatum, Jan 10 '17 at 20:13
Try with `progress = FALSE`. It seems to be called by [`ggmatrix_gtable`](https://github.com/ggobi/ggally/blob/ab0311e3c7cc959bec7f3b468094ed976af5c37c/R/ggmatrix_gtable.R), which takes a boolean `progress` argument. I'm not sure (haven't tested) if `progress = F` will be passed along deep enough. — Gregor Thomas, Jan 10 '17 at 20:34
@Gregor `progress = FALSE` in chunk option didn't work either. — adatum, Jan 10 '17 at 20:50
Not in the chunk option, in the `ggpairs` call. But no, it doesn't work. — Gregor Thomas, Jan 10 '17 at 20:57

The progress = FALSE argument will work when printing the ggpairs plot.

ggp = ggpairs(mtcars, columns = c("mpg", "cyl", "hp", "disp"))
print(ggp, progress = F)  # no progress bar
print(ggp)  # progress bar

It may also depend how you knit. The function that call the progress bar is ggmatrix_gtable, with the default value as

 progress = interactive() && (pm$ncol * pm$nrow) > 15

Thus no progress bar is printed by default in a non-interactive session.

Thank, this works! Re: knitting, I'm using the recently added `Preview Notebook` button in RStudio. – adatum Jan 10 '17 at 21:13

'progress' parameter in print function will soon be deprecated.

It can be passed to ggpairs itself:

library(GGally)
ggpairs(mtcars, 
        columns = c("mpg", "cyl", "hp", "disp", "am", "qsec"),
        progress = FALSE)

If you are familiar with dplyr syntax, maybe the following piping is the most elegant one which do not require saving intermediate variable

mtcars %>% 
  ggpairs(columns = c("mpg", "cyl", "hp", "disp", "am", "qsec")) %>%
  print(progress = F)
