Dear List,
how can I draw the following path diagram
A B C D E F
\ | / \ | /
G -- H
/ \/ \
I JK L
the problem I've got is that G and H need to be horizontally alingned
but the best I've done is diagonally or vertically alingned,
kind regards,
Rene

Dear List,
given a vecor of times in 5,15 and 30 minutes and a start point
in time, lets say 09:30:00, how do I add up those times
to the start time getting a cumulative time sequence?
mt-times(c('00:05:00', '00:15:00', '00:30:00'))
mt wanted
00:05:00 09:35:00
00:15:00 09:50:00
00:30:00
) + cumsum(mt)

Dear John and Duncan,
thanks for your ideas! Unfortunatly, calling spheres from rgl
did not resolve the problem on my machine.
Both - spheres3d() and rgl.spheres() -
behave the same: black spheres, all aqual colored.
The only difference beeing the looking angle and thebackround color.

I don't get scatter3d to color the sheres according to the '|' argument.

Dear All,
I have a binomial response with one continuous predictor (d) and one
factor (g) (8 levels dummy-coded).
glm(resp~d*g, data, family=binomial)
Y=b0+b1*X1+b2*X2 ... b7*X7
how can I get the inflection point per group, e.g., P(d)=.5
I would be grateful for any help.
Thanks in
|-b0
-b0=b1*X |/b1
-b0/b1=X
but I was hoping there might a more general solution for the case of
multiple logistic regression.

How can I run a constrained correspondence analysis with

15 animals were measured repeatedly month-wise (over to 2 years)
according to ther diet composition (8 food categories).
our data.frame looks like this:

dear all,
I want to make a dotplot with ratings from Items in 6 ItemsGroups.
I reordered the items by rating within each group.
I plotted the items by rating conditional on ItemGroup.
The ordering works as I wanted but my y-aches labels (items) within
each ItemGroup are now unequally spaced,
Dear All,
when I'm running a PCA with
prcomp(USArrests, scale = TRUE)
I get the right principal components, but with the wrong sign infront
Rotation:
PC1 PC2 PC3 PC4

UrbanPop 0.2781909
are along the same axis, only in a different direction. So there
is no problem :).
hope this helps,

Dear List,
I'm trying to draw vector in XYZ with rgl under use of a cylinder3d.
Therefore I scale and rotate a basis-cylinder).
However, somehow the rotation is wrong as
verified by overplotting arrow3d().
Where is my mistake?
library(heplots)
library(rgl)
# ... 2 vectors
=c(0,0,0),end=data[,2],'green')
arrow3d(c(0,0,0),data[,1],color='red');arrow3d(c(0,0,0),data[,2],
color='green')
axes3d(c('x','y','z'));title3d('main','sub','X','Y','Z');box3d()

Hello,
how can one merge two data frames when in the second data frame one
column defines the start values
and another defines the end value of the to be merged range.
data.frame.1
time ...
13
24
35
46
55
...
data.frame.2
start end
24 37 ?h? ?
...
should result in this
13 NA
24 ?h?
35 ?h?
46
(... once you fix the error in the example.)

Dear mixed modelers,
If I have interactions between a categorical
covariate and a random-effects grouping factor.
How can I test formally the correlations?
For example
data(Machines, package = MEMSS)
fm2aM - lmer(score ~ Machine + (0 + Machine|Worker), Machines)
Random effects:
Groups Name
Dear Everybody:
I want to test an interaction of two repeated measures in lmer()
I've response times (Y) from N subjects with two within-subject-factors.
aov(Y ~ A*B + Error(subjects/A*B), ...) shows an insigificant
interaction p(A:B) = .35
now lmer()
lm1 = lmer(Y ~ 1+A+B+(1+A*B|subjects),
Dear R community,
I've data-set with reaction times and count data (answers - yes, no)
of N subjects under conditions A, B.
For the analysis reaction time I used aov.
fit.rt = aov(rt ~ A * B + Error(subjects/(A*B)), data = m )
But how do I analyze the frequencies correctly?
example fable
,x,type=b)
# this fails ?
lines(approx(y,x),col=blue) # with xout = c(0:600)
thanks in advance,
René
