will be helpful for those in need I've googled around and I saw that if I use suppressPackageStartupMessages() I should be able to fix my issue, but turns out, nothing happened. , Not sure if anyone is still looking for an answer to this one but
I hope this helps you . Here are some things you can do to reduce the noise when loading packages with devtools::load_all: devtools::load_all(..., quiet = TRUE) handles messages for this single package, but not necessarily dependent packages
With these it helps Use the Source. If you look at the source code for sfLibrary, specifically where it prints those messages, you'll see that is uses sfCat. Tracing that down (same file), it uses cat.
