Haw I get best lambda in box-cox

"boxcox" in library(MASS).  I found it just now via "www.r-project.org" 
-> search -> "R Site Search" and via the index in Venables and Riply 
(2002) Modern Applied Statistics with S, 4th ed. (Springer).  The latter 
(p. 171-172) described how to make the corresponding profile likelihood 
plot using their function "logtrans".
