I have found a pair of functions, move and rm.sv, written by my colleague John Miyamoto very useful in managing one's workspace.

It is not clear to me that one can. If the singular value decomposition of A is the triple product P d Q', then the singular value decomposition of A'A=S is Q d^2 Q'. The information about...

Vera Hofer asks: " Dear colleagues, has anyone an idea how to carry out a nonparametric manova for comparing 3 groups? Thank you for your help. Vera" One approach would be to carry out a permutation test, randomly reassigning the vector...

Could I voice my support for the sixth point raised by John Fox? Many users would find such a development to be enormously useful. " (6) As has been pointed out, e.g., by Duncan Murdoch, solving the function-locating problem...

I would have expected the function getAnywhere to have behaved differently in the following: > search() [1] ".GlobalEnv" "file:C:/R/Rdata/miya/.Rdata" [3] "package:boot" "package:methods" [5] "package:ctest" "package:mva" [7] "package:modreg" "package:nls" [9] "package...

Dear Pedro, How to test for an interaction--or, even, how to pose the question of an interaction--in randomization-based inference is not at all obvious. And, in the permutation test context reliance has been placed on the exchangeability...

You may want to look at the notes on and functions for workspace management that guide me. They can be downloaded from http://faculty.washington.edu/lunnebor/Stat342/ by checking on "Exercises." I use the .GlobalEnv (position 1 on search...

I have found the use of save( ) and attach( ) when supported by a pair of functions written by my colleague John Miyamoto, move( ) and rm.sv( ) quite useful in managing (1) collections of useful homebrew functions, (2) project workspaces, and...

As an alternative to the use of multiple shortcus to gain entry to different R environments on WIndows platforms I would like to suggest the use of two R functions written by my colleague John Miyamoto. I have taken the...

I am having difficulty coming to grips with Appendix B.2 of the otherwise very useful "An Introduction to R" and the related help file for Startup. I am running RGui 1.6.0 on a Windows 2000 machine from...
