@Drmowinckels Oh yeah that's a bit of a hack. My .Rprofile has a line in it that clears the screen (and with it the default startup message):

cat("\014")

After that, I write my own startup message like this:

cli::cli_alert(R.version.string)
cli::cli_alert(paste("Running under", utils::osVersion))
cli::cli_alert(paste("System time is", as.character(lubridate::now())))
