cat() is somewhat special in that, by default, it does not output
a new line after each element in the list being output:

  cat("A B C","D E F","G H I")
  # A B C D E F G H I

However, you can get it to inset one by using the "sep" argument
(default sep = " " as in the above output):

  cat("A B C","D E F","G H I",sep="\n")
  # A B C
  # D E F
  # G H I

See the description in '?cat'. The name "cat", as in UNIX 'cat',
is an abbreviation for "catenate", which means to string things
together in a chain. Hence the default behaviour above (but with
spaces inserted to separate the original elements). For a true
catenation, with nothing separating the chained elements, see:

  cat("A B C","D E F","G H I",sep="")
  # A B CD E FG H I

Hoping this helps.
Ted.
