I was trying "quantreg" package, lm1 <- lm(y~x) rq1 <- rq(y~x) plot(summary(rq1)) #then got a warning says singular value, etc. but this line can be omited plot(lm1) #crash here It happened every time on my PC, Windows XP Pro Serv. Pack 1, Pentium(4) 3.00G. [[alternative HTML version deleted]]
I forgot to mention my R version is 2.3.1 and quantreg is the most updated too.

Since the "crash" occurs plotting the lm object it is unclear what this has to do with quantreg, but maybe you could explain 1. what you mean by crash, 2. something about x,y, This is best addressed to the maintainer of the package rather than to R-help, provided, of course, that it is really a question about quantreg. url: www.econ.uiuc.edu/~roger Roger Koenker email rkoenker at uiuc.edu Department of Economics vox: 217-333-4558 University of Illinois fax: 217-244-6678 Champaign, IL 61820 On Jun 7, 2006, at 2:32 PM, Mu Tian wrote:> I was trying "quantreg" package, > > lm1 <- lm(y~x) > rq1 <- rq(y~x) > plot(summary(rq1)) #then got a warning says singular value, etc. > but this > line can be omited > plot(lm1) #crash here > > It happened every time on my PC, Windows XP Pro Serv.

Without y and x we cannot reproduce this.

I attached the data file here. I restarted the PC but it still happens. It says a memory address could not be written. I am not sure it is a problem of R or quantreg but I plot without problems before I load quantreg. Thank you.
