Help with possible bug (assigning NA value to data.frame) ?
There's something peculiar that I do not understand here. However, did you
realize that the thing you are assigning into parts of `a' is NULL? Check
you're my.test.boot.ci.1: It's NULL.
Be that as it may, I get:
> a <- data.frame(matrix(1:4, nrow=2), X3=NA, X4=NA)
> a
X1 X2 X3 X4
1 1 3 NA NA
2 2 4 NA NA
> a[a$X1 == 1,]$X3 <- NULL
> a
X1 X2 X3 X4

Animal Morphology: Deriving Classification Equation with Linear Discriminat Analysis (lda)
Fellow R Users:
I'm not extremely familiar with lda or R programming, but a recent editorial
review of a manuscript submission has prompted a crash cousre. I am on this
forum hoping I could solicit some much needed advice for deriving a
classification equation.
I have used three basic measurements in lda to predict two groups: male and
female. I have a working model, low Wilk's lambda,

NV50 compute support questions
Well, if you remove that assert locally, all compute tests in
src/gallium/tests/trivial/compute.c pass on GK106, except the atomic
ones. I'm working on the fermi case btw.

Do you mean the:
Assertion `pres->target != PIPE_BUFFER' failed.
or the:
Assertion `tex->defExists(0) && tex->srcExists(0)' failed.
assert? Or is the first one not present for

Tapply for Group Specific Means and Proportions
UseRs,
I am working on a dataset (see small example below) where individuals
were followed on a specific date-time combo and multiple repeated
measurements were taken (e.g., height in meters, behavior class in 2
letter code). Observation numbers varied between individual (ranging
from 1 observation for each date-time combo to >50)
I am trying to summarize the data into 1 row per

Confidence intervals for relative risk
Wolfgang,
It is common to handle relative risk problems using Poisson regression.
In your example you have 8 events out of 508 tries, and 0/500 in the second
data set.
> tdata <- data.frame(y=c(8,0), n=c(508,500), group=1:0)
> fit <- glm(y ~ group + offset(log(n)), data=tdata, family=poisson)
Because of the zero, the standard beta/se(beta) confidence intervals don't
work.

doSMP package works better than perfect, at least sometimes.
Some might have noticed that REvolution Computing released the doSMP
package to the general public about a month and a half ago, which allows
multiple cores to be accessed for parallel computation in R. Some of our
physical habitat calculations were taking an extraordinary amount of time
to complete and required over-weekend runs, which prompted our interest in
this package. What follows
