Round a line

R-help,

I have lloked in the archives found no answer to how to round the line
joint.

I have usedthe arguments lnd, ljoin in par but I get no differences in
the plotting.

x=1:10
par(ljoin="round",lend="round")
plot(x,sin(x),type="l",lwd=2)


Any suggestions?

Well, round is the default! You have to zoom in or make even thicker 
lines. Hence you might want to try out the folowing to see differences:

   x <- 1:10
   par(mfrow = c(1, 2))
   plot(x, sin(x), type="l", lwd=10)
   par(ljoin="mitre", lend="butt")
   plot(x, sin(x), type="l", lwd=10)

R-help,

I have lloked in the archives found no answer to how to round the line
joint.

the plotting.

x=1:10
par(ljoin="round",lend="round")

On my Windows 2000 machine using R 2.1.0, par()$ljoin and par()$lend are
already "round" by default.  The par()$lmitre parameter is 10,

Paul Murrell's article "Fonts, lines, and transparency ..." in R News 4/2
(Sept 2004) gives some clues under "The end of the line":
http://cran.stat.auckland.ac.nz/doc/Rnews/Rnews_2004-2.pdf



"All lines are drawn using a particular style for line ends and joins,
though the difference only becomes obvious when lines become thick."



Is it possible that with par()$lmitre at 10, and a lwd=2, you won't see any
difference?
