R help - Jul 2007 - can I paste 'newline'?

It is ok to bury a reg expression '\n' when using 'cat', but not
'paste'.
e.g.

cat ('I need to move on to a new line', '\n', 'at here')
# change line!
paste ('I need to move on to a new line', '\n', 'at
here') # '\n' is just a
character as it is.

Is there a way around pasting '\n' ? Thanks a lot.

What do you want to get?  Do you want a two element vector?  Then use 
c().  Do you want a one element vector that prints on two lines?  Use 
either form, they both work (but you need to use cat() to do the display).

 > x <- paste ('I need to move on to a new line', '\n',
'at here')
 > cat(x)
I need to move on to a new line
  at here>

Notice the difference:
> cat ('I need to move on to a new line', '\n', 'at
here') # change line!
I need to move on to a new line
 at here> paste ('I need to move on to a new line', '\n',
'at here') #
'\n' is just a
[1] "I need to move on to a new line \n at
here"
> cat(paste ('I need to move on to a new line', '\n', 'at
here'))
I need to move on to a new line
 at here>
> paste("a long string
+ with carriage
+ returns")
[1] "a long string\nwith carriage\nreturns"
>

> cat(paste("a long string

+ returns"))
a long string
with carriage
returns>


paste is showing you the characters in the string; cat is acutally
outputting to a print device where '\n' is a line feed.
