Hmisc Latex Question: column headings and Major Column Headings not properly alligned
Dear R users:
When I create a table without Major Column headings, my *regular* column headings appear correct in the typeset latex file. The major row heading and row groups are as they should.

Spaces in a name
I am reading regressors from an excel file (I have no control over the file)
and some of the element names have spaces:
i.e. "Small Bank Aquired"
but I have found that lm(SourceData ~ . - "Small Bank Aquired", mcReg)
doesn't work (mcReg = modelCurrentRegressors)
As they are toggles I have ran them through factor() to be treated propertly
as 0 or 1 but due to the fact I

Overdispersed poisson - negative observation
Dear R users
I have been looking for functions that can deal with overdispersed poisson
models. Some (one) of the observations are negative. According to actuarial
literature (England & Verall, Stochastic Claims Reserving in General
Insurance , Institute of Actiuaries 2002) this can be handled through the
use of quasi likelihoods instead of normal likelihoods. The presence of
negatives is not

Minor bug in lillie.test from nortest package (PR#9784)
Full_Name: David Sterling
Version: 2.4.0
OS: OS X
Submission from: (NULL) (64.81.102.199)
lillie.test() dies without grace producing the error message: 'Error in if
(pvalue > 0.1) { : missing value where TRUE/FALSE needed' when passed a vector
of identical values.
Examples:

Question about linear regression in R
Hi all,
I wrote a r program as below:
x <- 1:10
y <- c(3,3,3,3,3,3,3,3,3,3)
fit <- lm(log(y) ~ x)
summary(fit)
And I expect to get some error message from R, because "y" is constant.
But, I got the message as below:
> summary(fit)
Call:
lm(formula = log(y) ~ x)
Residuals:
Min 1Q Median 3Q Max

Post Hoc Groupings
Quick question, as I attempt to learn R. For post-hoc tests
1) Is there an easy function that will take, say the results of
tukeyHSD and create a grouping table. e.g., if I have treatments 1, 2,
and 3, with 1 and 2 being statistically the same and 3 being different
from both

Multiple histograms one graphic device & groupings
Hello,
I am trying to produce some graphics to visualize my data. I think I want
histograms. I have a grouping variable that has 48 different groups. I would
like to produce a graphic that contains three of of these groups in the same
device (they are time steps). I would like create graphics for about 6
different variables (6 variables X 16 groupings of there = 96 graphics). I

How to extract rows from data frame based on unique variable groupings
R community,
I would like to know how to extract rows from a data frame (DF) such that
each row in the new data frame (D.F) represents the first instance of
a unique variable pairing in the original dataframe (ordered first by
variable V1 then by variable V2). The unique function does not seem
to be able to accomplish this. I imagine there must be a simple solution for this,
but I can't

lmer with nested/nonnested groupings?
I'm trying to figure out how to use lmer to fit models with factors that
have some nesting and some non-nested groupings. For example, in this
paper:

Turning pass/fail results into a proportion
Please forgive me, I feel exceptionally like a newbie. Although I've
read screeds of documentation, I just can't see how this is done.
I have a data frame that contains a number of pass/fails for certain
variable sizes. From that, I would like to form another data frame that
contains the proportions of pass/fails per variable.
So, for example:

Help With ANOVA

I have a problem with My ANOVA

I have created a list (zzzanova) which contains

[LLVMdev] scoreboard hazard det. and instruction groupings
I'm considering writing more-detailed itineraries for some PowerPC CPUs
that use the 'traditional' instruction grouping scheme. In essence,
this means that multiple instructions will stall in some pipeline stage
until a complete group is formed, then all will continue.
I expect to provide CPU-specific code to help determine when the
currently-waiting instructions would form a group.
