Sorry to chime in; I had wanted to bring this to Brian's attention a few days ago, but always got side-tracked: Here are results on my IBM/Lenowo X41 notebook model name : Intel(R) Pentium(R) M processor 1.50GHz cpu MHz : 600.000 bogomips : 1198.37 MemTotal: 1546600 kB with *no* graphics acceleration: Everything is local but not really fast hardware > F <- ecdf(rnorm(10000)) > system.time(plot(F)) user system elapsed 3.204 0.024 3.402 > x11(type="Xlib") > system.time(plot(F)) user system elapsed 0.068 0.000 0.354 > which is somewhat dramatic, and for tk*() pseudo-animations, I have definitely needed to use type = "Xlib" Martin >> R version 2.8.0 Under development (unstable) (2008-04-05 >> r45102) >> >> Thank you again for tracking down the original issue. >> >> Martin >> >> Prof Brian Ripley <[EMAIL PROTECTED]> writes: >> >>> I think I have found this -- if so, it was an X11 timing >>> issue and we needed to re-read the X11 window size at a >>> later time.
