Clear startup screen in R / RStudio

Question

I would to change the start up/ logon screen that I get when I first open up R or actually Rstudio. What I would like to have is just the '>' prompt and nothing else.

I know I have seen this on the web before but can't remember what the search phrase was.

I should have added that I am using Ubuntu Linux 10.04!
Any suggestions?

Other guys are giving you advice how to stop the messages, I will take it the other way: how to clear the console. You can press Ctrl-L manually. Of course, it would be nice to do this programmatically and place the appropriate command at the end of your system .RProfile. I tried the obvious solution:

cat("\014") # or cat("\f")

but this apparently doesn't work. You can do this:

cat(rep("\n", 50))

which will clean your console, but the cursor is at the last line. Or you may try the solution proposed here (I've not tested it though - please report if it works if you try it):

cls <- function() {
       require(rcom)
       wsh <- comCreateObject("Wscript.Shell")
       comInvoke(wsh, "SendKeys", "\014")
       invisible(wsh)
} 

On linux console, the following could work:

system("clear")
