Re: [R] confidence intervals for orthogonal contrasts

[James Henson]

Richard,

Thanks, Have not previously used the HH package, but looks as if it
contains many useful tools.  Will check out your book also.

Best regards,
James

Re: [R] confidence intervals for orthogonal contrasts

James,

Please look at the maiz example, the last example in ?MMC
help("MMC", package="HH")
where I show how to construct and calculate a set of orthogonal contrasts
for a factor in an analysis of variance setting.  mmc and mmcplot use glht
in the multcomp package for the underlying calculations.

If yo don't have HH, you can get it with
install.packages("HH")

See the references in ?MMC to my book and paper.  The second edition
of the book is now available.
