Sorry, let me provide the details:
My package has a .onAttach function (not a .onLoad). The .onAttach
constructs a startup message and delivers it via packageStartupMessage().
I've pasted the code below. My package has a number of other packages
in Depends and Imports. Some of the packages in Imports have startup
message (not R message, but package specific messages).
For example I have PerformanceAnalytics in Imports and it shows:
"Econometric tools for performance and risk analysis.
..."
And nothing happenms once you start it via
suppressPackageStartupMessages( library("PerformanceAnalytics"))
right?

googoleVis shows:
"Please read the Google Visualisation& Maps API Terms of Use
before you use the package:
..."
my .onAttach is pretty simple:
.onAttach<- function(...)
{
mylib = dirname( system.file( package = "spear" ) )
ver = packageDescription( "spear" , lib = mylib )$Version
builddate = packageDescription( "spear" , lib = mylib )$Date
startupMessage = ""
startupMessage = paste( startupMessage , "\n\n\n" , sep = "" )
startupMessage = paste( startupMessage ,
"--------------------------------------------------------------------------------------------------------------------\n"
, sep = "" )
startupMessage = paste( startupMessage , "SPEAR\n" , sep = "" )
startupMessage = paste( startupMessage , paste( "(Version " , ver , ",
built: " , builddate , ")\n\n" , sep = "" ) , sep = "" )
startupMessage = paste( startupMessage , "MY MESSAGE HERE...left out
for brevity" , sep = "" )
packageStartupMessage( startupMessage )
}

There are / were are few issues intertwined in my case, and yours may
differ:
- are the messages from your code / packages and you startup messages ?
- are they from imported packages ?
- are they from R (reported 'foo being shadowed' or 'generic bar defined')
In my case a combination of using .onAttach and .onLoad (instead of just
.onLoad) together with import directives in a NAMESPACE file solved the
issue, as had been suggested on this list.
