I noticed that RMarkdown's chunk option message=FALSE does not work on my (also on my colleague's ) environment and could not find its reason.
I tried the most simple example written in 11.7 Hide code, text output, messages, or plots | R Markdown Cookbook , and I can see its message though.
message("You will not see the message.")
I'm not sure what is going on.
I appreciate any hints or suggestions.
Here is my environment.
Windows 10
R version 4.0.5 (2021-03-31) -- "Shake and Throw"
Platform: x86_64-w64-mingw32/x64 (64-bit)
RStudio 2021.9.0.351
rmarkdown : 2.11
knitr: 1.36
rlang: 0.4.11
PS)
Also tried with R-4.1.1 or RStudio 1.4.1717 (not successful).
suppressMessages() is not the best solution.
warning=FALSE works well.
