Best wishes,

I'm bringing this issue to r-devel as my idea of sending it to r-help
appears to be wrong.
The following is reproducible in R-patched and R-devel (also in older
versions).
An outlier is inserted in group E and the last plot by plot.lm suggests
that the point belongs to D.
It appears to me that:
* (facval, rsp) and
* x$xlevels[[1L]][order(sapply(split(yh,mf[,1]), mean))]
are sorted differently.
set.seed(2)
a <- rnorm(50,0,2)
x <- rep(seq(10, 50, by=10), each=10)
y <- x+a
f <- rep(c("e","a","c","b","d"), rep(10,5))
f <- as.factor(f)
y[1] <- 200
mod1 <- aov(y ~ f)
par(mfrow=c(2,2))
plot(mod1)
My latest attempt was on:
