Correct, nothing happens in terms of startup messages. No messages are
shown.
library( my package ) # Performance Analytics message shown
search() # PerformanceAnalytics is not in the search list since its in my

suppressPackageStartupMessages**( library("PerformanceAnalytics"**)) # no
message are shown
search() # PerformanceAnalytics is now in the seach list beneath R_Global
as expected
