index.cond in xyplot
Dear R-users
I have 5 dependent variables (y1 to y5) and one independent variable (x) and
3 conditioning variables (m, n, and 0). Each of the conditioning variables
has 2 levels. I created 2*4 panel plots.
xyplot(y1+y2+y3+y4+y5 ~ x | m*n*o,layout = c(4,2))
I would like to reorder the 8 panels. I tried to use index.cond (e.g.,

Logit Regressions, Clustering etc
...rrying out some logit regressions and want to (a) make sure I'm
taking the right approach and (b) work out how to carry out some additional
analysis. So, to carry out a logit regression where the dependent variable
is a factor db, I use something like:
res1_l <- glm(formula = db ~ y1 +
+ y5, family = binomial(link = "logit"))
summary(res1_l)
...which is, I hope correct. I also need to carry out an ordered logit

help with a regression
Hello, I have a data frame with the following variables:

MANOVA and Extra Sums-of-Squares Tests
I would like to conduct an extra sum-of -squares test that compares a full
MANOVA model (with all 1st order interactions) to a reduced model (no
interactions) to determine if I can drop all interactions at the same time.
This is analagous to an extra sum-of-squares F-test in ANOVA, but instead
using MANOVA. Is there a command in R that does this? If not, is there a
command that calculates

macro facility in R
...2.2 on windows XP
I have a dataset with multiple columns. Some of the columns represent
independent variables, some represent dependent variables. I would like
to run the same analyses on a fixed set of independent variables,
changing only the dependent variable, e.g.
y1-y2=x1+x2+x3
y3-y4=x1+x2+x3
y5-y6=x1+x2+x3, etc.
I know I can write a function to perform the analyses, however in order
to make the analyses easy to do, I really need a macro scripting
language that will allow preprocessing of the function and substitution
of macro variables with parameters passed to the macro, i.e. I need

between them as they all have a common x-axis.
However, using the code below I'm unable to get the plot area the same size
for each plot.
The bottom plot with the x-axis label is smaller than the others, as is the
top plot which has larger margins.
How can I get the plot region the same size for
