Greg,
It might be better to use ylim = c(min(x), 0)
in place of ylim = c(-4, 0). I don't think plt can take
negative values.

Hi Max,
You have 'title' as a component of the 'text' component of key.
According to the help page for xyplot, 'title' is a component
of key. AFAICS, 'text' does not have a 'title' component.

mtext() is not a lattice function. Could you not use the 'main'

Looks like a bug (in mvt()?). Note that
pmvnorm(lower = c(-Inf, -Inf), upper = c(Inf, 10))
works as expected, as does replacing any of the 4 Infs with a finite
value.
Function sadmvn() in pkg:mnormt does give 1 with Inf lower/uppers.

Sara,
You didn't read your data into R correctly.
If your data are really in the form you posted (one long column
of mixed data types and lots of blank lines), then I would:
1. remove the blank lines with my text editor and save (say, mydata.txt)
2. scan() the variable names into a vector

Asako,
My copy of MASS4 has been borrowed. But you can have a look at
Julian Faraway's "Practical Regression and Anova using R" in

In MASS, look for 'vcov'.

Maybe you did something strange when you "replaced Y1's values ".
Is the result a 10-level factor?
The following works for me.

Good point. I actually keep packages that aren't installed with

I assume that 'tab' is a data frame and that, for some
unspecified reason, you want to get two subsets of the last
column of tab, overlapping one case, and coercing the final
result to a data frame. If that is correct, then
as.data.frame(c(tab_tmp, tab_tmp1))
will give you a data fram

1. I've seen several intro-stats textbooks that define a

and then define Tukey's boxplot as a "modified" boxplot.
I wish authors wouldn't do that.
