[R] Plot can't forget bad parameters
When I give plot some bad paramaters, it keeps giving me error messages forever after. I think the last time this happened, I even got the error messages for completely unrelated, non-graphical functions. Here's a recent example: plot(it[[31]][,c(1, 3)], type=b, usr=c(0, 20, -20, 5)) Warning messages: 1: parameter usr couldn't be set in high-level plot() function 2: parameter usr couldn't be set in high-level plot() function 3: parameter usr couldn't be set in high-level plot() function 4: parameter usr couldn't be set in high-level plot() function 5: parameter usr couldn't be set in high-level plot() function 6: parameter usr couldn't be set in high-level plot() function plot(it[[31]][,c(1, 3)], type=b, ylim=c(-20, 5)) Warning messages: 1: parameter usr couldn't be set in high-level plot() function 2: parameter usr couldn't be set in high-level plot() function 3: parameter usr couldn't be set in high-level plot() function 4: parameter usr couldn't be set in high-level plot() function 5: parameter usr couldn't be set in high-level plot() function 6 Is this a bug, or have I missed something?

R 1.7.1 It's to do with redrawing. When the graphics device is redrawn on the screen (eg if it is covered up and then exposed) the commands that created it are replayed. (in fact, I think they may be replayed twice on some systems). It's not entirely a bug, since the redrawing is necessary: we don't keep a bitmap, and even if we did we'd have to redraw on resize. Suppressing warnings on the redraw would make sense, though. After you do a new plot the warnings should stop resurfacing. -thomas __ [EMAIL PROTECTED] mailing list https://www.stat.math.ethz.ch/mailman/listinfo/r-help

R 1.7.1 Well, that's very odd. I did the rm(), and it printed out the warnings again. Then I repeated the two commands above--only this time, there were no warnings after the second (i.e., things worked OK). __ [EMAIL PROTECTED] mailing list https://www.stat.math.ethz.ch/mailman/listinfo/r-help
