How do I silence this particular R message?

Question

I am running an R function within a third-party software package. (The third-party package uses an older version of R, version 3.6). The output I am passing along is:

library(tidyverse)
theOutput <- x %>%
  left_join(y, by = "id")

However, the output I am getting from the package is this notification, which I see in RStudio whenever I do a join, Joining, by = "id". How do I silence this message such that it will not be passed along as output? I tried

options(tidyverse.quiet = TRUE)

but it does not seem to stop the join message.

(Also, if the only answer is "your third party needs to use the newest version of R," I understand, but that is unfortunately impossible.)

Does this help, https://stackoverflow.com/questions/16194212/how-to-suppress-warnings-globally-in-an-r-script — Boudu, Sep 15 '22 at 19:39
Unfortunately not. The Join notification does not appear to be considered a "warning." — markyoung, Sep 15 '22 at 19:48

We can use suppressMessages. First, let's recreate your issue:

library(dplyr)

df1 <- data.frame(letter = c("A", "B", "C"), data  = 1:3)
df2 <- data.frame(letter = c("A", "B", "C"), value = 4:6)

df1 %>%
  left_join(df2)
#> Joining, by = "letter"
#>   letter data value
#> 1      A    1     4
#> 2      B    2     5
#> 3      C    3     6

Note we have the "Joining, by" message. But if we add suppressMessages to the pipe after our left join

df1 %>% 
  left_join(df2) %>%
  suppressMessages()
#>   letter data value
#> 1      A    1     4
#> 2      B    2     5
#> 3      C    3     6

It disappears.

this worked as desired. Thanks very much. – markyoung Sep 15 '22 at 20:14

Another way to suppress all messages is `options(rlib_message_verbosity = "quiet")`. – user2554330 Sep 15 '22 at 20:30

@user2554330 that's a good tip, though for safety it's usually better to handle specific messages you know you want to ignore. – Allan Cameron Sep 15 '22 at 20:35
