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 suppressWarnings(suppressMessages(library("dplyr")))
import_library = function(lib_name){
suppressWarnings(suppressMessages(require(lib_name, character.only = TRUE)))
}
import_library('dplyr')

Suppress loading messages when calling function directly (not loading package in full)

around this issue Thought I'd tried this before but apparently not. Both of these options work: p <- suppressMessages(raster::rasterToPolygons(r, dissolve = TRUE))
p <- suppressPackageStartupMessages(raster::rasterToPolygons(r, dissolve = TRUE))

R package development how to suppress messages generated from dependency package?

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 .onLoad <- function(libname, pkgname) {
invisible(suppressPackageStartupMessages(
sapply(c("tibble", "purrr", "dplyr", "tidyr", "ggplot2", "data.table"),
requireNamespace, quietly = TRUE)
))

Suppress start-up messages when loading a library to snowfall cluster with sfLibrary
Date : March 29 2020, 07:55 AM
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. cat("quux4\n")
# quux4
invisible(capture.output(cat("quux5\n")))
cat("quux6\n")
# quux6
cat("quux1\n")
# quux1
sink("ignore_me.txt")
cat("quux2\n")
sink(NULL) # remove the sink
cat("quux3\n")
# quux3
else {
## Load message in slave logs.
sfCat( paste( "Library", .sfPars$package, "loaded.\n" ) )
## Message in masterlog.
message( paste( "Library", .sfPars$package, "loaded in cluster.\n" ) )
}
