apply with a division
Hi,
I'd like to normalize a dataset by dividing each row by the first row.
Very simple, right?
I tried this:

X1 X2 X3
1 124 120 134
2 165 163 174
3 52 51 43
4 179 171 166
5 239 238 235
>first.row <- expt.fluor[1,]
> normed <- apply(expt.fluor, 1, function(r) {r / first.row})
>normed

plot3d, color points by group
Hello
I've created a 3d scatterplot, and had no problems labeling the points.
However, I've been really struggling to change the color of the points based
on a factor (see 'group' below). Is such a thing possible?
My data look like this:
food group x y z
apple fruit 0.216 -0.112 -0.893
orange fruit 0.814 0.097 0.460
broccoli veg -0.239 0.240 -0.425

stacking consecutive columns
I have a file, each column of which is a separate year, and each row of each column is mean precipitation for that month. Looks like this (except it goes back to 1964).

how to interpret the results of a simint call
Hi all,
I've done some anovas, found some significance and proceeded to do the
post hoc tests to determine the source of the significance. I used the
multcmp package as suggested by Andy Liaw (thank you).
I am, however, unsure how to interpret the results of the call to
simint. Could someone help me with this?
I've attached the code and the results it produced. There are 3 groups

AIC from coxme
Hi,
I am running the following model:
fit1.full <- coxme(Surv(age_sym1, sym1) ~ sex + lifedxm*sex + (1|famid),

I would like to extract the AIC from that object to calculate the AICC.
However, when I look at str(fit1.full) and summary(fit1.full) (pasted
below) I don't see anything that would allow me to get pull the AIC out
from that object.
Is there a way to retrieve the

Hi all,
I'm seeing this failure on my PPC G4 box running TOT with llvm-gcc

Multiple Comparisons-Kruskal-Wallis-Test: kruskal{agricolae} and kruskalmc{pgirmess} don't yield the same results although they should do (?)
Hi there,
I am doing multiple comparisons for data that is not normally distributed.
For this purpose I tried both functions kruskal{agricolae} and
kruskalmc{pgirmess}. It confuses me that these functions do not yield the
same results although they are doing the same thing, don't they? Can anyone
tell my why this happens and which function I can trust?

Systematically biased count data regression model
Dear all,
I am attempting to explain patterns of arthropod family richness
(count data) using a regression model. It seems to be able to do a
pretty good job as an explanatory model (i.e. demonstrating
relationships between dependent and independent variables), but it has
systematic problems as a predictive model: It is biased high at low
observed values of family richness and biased low at

How to sum values across multiple variables using a wildcard?
I have a dataframe called "data" with 5 records (in rows) each of
which has been scored on each of many variables (in columns).
Five of the variables are named var1, var2, var3, var4, var5 using
headers. The other variables are named using other conventions.
I can create a new variable called var6 with the value 15 for each
record with this code:
> var6=var1+var2+var3+var4+var5

... and the mailing list is picky about attachments... whatever you attached did not conform to the stringent requirements mentioned in the Posting Guide. Pasting the code right into the email is usually safest, though you DO have to post using plain text (as the Posting Guide indicates) or your code may get mangled by the automatic html format removal.

smarter folks than I on it who can help.
I may or may not have time to look at this. Hopefully someone else will.
