R help - Oct 2007 - Sweave line length

Hello,

I am trying to add R code to my dissertation and the length of a line 
of text that Sweave generates is longer than the right margin in my 
dissertation.  I have found no way to tell Sweave how to set the line 
length.  I am using an iMac with tiger ver. 10.4.10, and R: ver. 
2.5.1.  Here is the R code that is longer than my right margin:

input to Sweave:
legend("topleft",c("obs",
"theo","hi","lo"),lty =
c(1,2,3,4),col=c(1,2,6,4,0), cex=1.5,pt.cex=c(3,6), bty='o',inset=.05)

output from Sweave:
>  legend("topleft", c("obs", "theo",
"hi", "lo"), lty = c(1, 2, 3,
>4), col = c(1,
+     2, 6, 4, 0), cex = 1.5, pt.cex = c(3, 6), bty = "o", inset =
0.05)

The line is about eleven (11) characters too long.

Thanks,

Keith Jones

I'm not sure if it affects the echoed commands too, but inserting a code
chunk like

<<>>
options(width=60)
@

(replace 60 with the width you need) controls the width of the R output.
