R help - Jun 2011 - Use line break at scrip but avoid line break on graphics

Hello list,

I have plots with long strings in main=, ylab= or xlab=. So, in I my script
I use break long lines to avoid lines hiden on my monitor and in sweave
document pages. I use graphics like this

plot(1, main="aaaaaaaaaaaaaaaaaaaa
              bbbbbbbbbbbbbbbbbbbb")

but I would like a plot result like this

plot(1, main="aaaaaaaaaaaaaaaaaaaa bbbbbbbbbbbbbbbbbbbb")

I remember once I saw a meta character like "\n" that avoid this
breack line

plot(1, main="aaaaaaaaaaaaaaaaaaaa\(?)
              bbbbbbbbbbbbbbbbbbbb")

Does someone know that?

Thanks.
Walmes

I think that

     plot(1,main=paste("aaaaaaaaaaaaaaaaaaaa",
                                    "bbbbbbbbbbbbbbbbbbbb"))

might do what you want.

I think he needs

plot(1,main=paste("aaaaaaaaaaaaaaaaaaaa\n",
                                 "bbbbbbbbbbbbbbbbbbbb", sep =
""))

or simply

plot(1, main="aaaaaaaaaaaaaaaaaaaa\nbbbbbbbbbbbbbbbbbbbb")

Look, Ma, no quotes!  Er, well, maybe one "quote".

plot(1, main=quote(aaaaaaaaaaaaaaaaaaaa~
                       bbbbbbbbbbbbbbbbbbbb) )

I suspect you are thinking of LaTeX or some other language; as far as I 
know there is no way to avoid including the break within a string in R 
source files.

There is one slightly ugly possibility if you are using Sweave:  put the 
source all on one line, but then post-process the output to wrap it.
