[S] lines() problem

[David Maxwell FSMG CEFAS <D.L.Maxwell@cefas.co.uk> (DN=DLM00, RECIPIENTS, LOWESTOFT, CEFAS)]

Using SPlus 4.5 r2  on Win95,

I have noticed that lines( ..., type="l") and lines(..., type="b") treat points 
outside the y-limits differently and therefore produce different lines for the 
same data. Is this a well-known 'feature' ?

A simple example of this:

par(mfrow=c(2,1))

plot(0, 0, type="n", xlim=c(1,6), ylim=c(2,6) )
lines(1:6, c(3,0,3,8,2,4), type="l" )

plot(0, 0, type="n", xlim=c(1,6), ylim=c(2,6) )
lines(1:6, c(3,0,3,8,2,4), type="b" )


I would like type="l" to produce the same shape line as type="b" does. I've 
been using type="b", cex=0.001  as a quick way round it. Any other suggestions 
(except changing the y-limits :o) ) would be welcome.

Thank you, David.
