How to get interction terms first in a model
Consider the following two specifications of a model:
library( splines )
x <- 1:100
y <- rnorm( 100 )
w <- rep( 1, 100 )
A <- factor( sample( 1:2, 100, replace=T ) )
B <- factor( sample( letters[1:4], 100, replace=T ) )
summary( lm( y ~ ns( x, knots=c(30, 50, 70 ), intercept=T ):A - 1 + B )
)
summary( lm( y ~ ns( x, knots=c(30, 50, 70 ), intercept=T ):A - 1 + B:w
) )

2.2.3a PDC Win2K Citrix Profiles
...oaming to Local, then there are
no files saved in their Profile Folder on SAMBA but is saved just on the
Win2K Server and a WINDOWS\system folder is still created in their
SAMBA Home Folder and contains several files. The Profile Folder is not
created if it doesn't exist.
This may be how Win2K intercts with SAMBA PDC, but the 0700 dir mask is
wrong
and a user's Profile Folder is created with user:root and group:<user> by
default so 0700 would never allow the user access.
If you remove 'logon path = ' and don't create a [profiles] share in
smb.conf, you get the profiles sav...

I have a significant effect of selection line. Eyeballing the
interction.plot, it is clear the the line called "25" is smaller at both
temperatures than the other lines.
but when I check the contrasts with summary(mod1) I get:

Lisp-stat and R? [was: Re: Status?]
...adept Lisp-stat programmer. But I
have worked on or used several projects for which Lisp-stat seemed the ideal
environment-- for implementing relatively portable, state-of-the-art
applications, using dynamically-linked graphic windows to provide
and demonstrate leading-edge examples of highly-interctive environments
for the whole range from testing new ideas to delivering course content,
as has been done with Arc and ViSta.
My work with Forrest Young and Pedro Valero on ViSta implementations
of mosaic displays and other methods for categorical data has been
particularly gratifying, in that we&...
