[R] Warning message when starting RStudio

Hi list Recently, when starting up RStudio, the following warning is being displayed: Error in tools:::httpdPort = 0L : comparison (4) is possible only for atomic and list types I think that this is specific to RStudio because starting R in a terminal window doesn't produce this message.
