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?
