Advice on recoding a variable depending on another which contains NAs
Dear colleagues,
I would be very grateful for your help with the following. I
have banged my head off this question several times in the
past, and repeatedly over the last week. I have looked in
the usual places and found no obvious solution. I fear that
this just means I didn't recognize it, but I'd be very
grateful for your help.
I am scoring 8000 psychometric tests - the SCQ, if

[LLVMdev] RFC: ErLLVM - Implemented HiPE Calling Convention
This patch (and the others that will follow) are rebased on svn r155440:
"AVX2: The BLENDPW instruction selects between vectors of v16i16 using an i8
immediate. We can't use it here because the shuffle code does not check that
the lower part of the word is identical to the upper part"

Hi Kostis,
Just to check, did you send the patch originally to llvmdev or llvm-commits?
The latter is where all commit review takes place.
Cheers,

HiPE calling convention
Hi all
I saw presentation http://www.softlab.ntua.gr/~gtsiour/files/erllvm_pres-20111107.pdf

That presentation mentioned that:

[LLVMdev] RFC: ErLLVM - An LLVM backend for Erlang
Hi,
We 've been working on an LLVM backend for High Performance Erlang (HiPE) [1],
the native code compiler of Erlang/OTP [2]. ErLLVM [3] targets the X86 and AMD64
architectures for now but there is some ongoing work from a team on the Uppsala
University to also support ARM. In our implementation, we have paid special
attention on retaining ABI-compatibility with the Erlang Runtime System in

[LLVMdev] RFC: ErLLVM - An LLVM backend for Erlang
Hi,
Following Chris' advice, I will rebase the patches and break them in 3 distinct
emails (one at a time) in order to be easier for a reviewer to
approve/comments. Please note that the three patches while being code-wise
independent, they 're strongly-connected *semantically*, meaning that including
just a subset of these patches to LLVM's code base is quite weak if the others

Appropriate test for overdispersion in binomial data
Dear R users,
Overdispersion is often a problem in binomial data. I attempt to model a
binary response (sex-ratio) with three categorical explanatory variables,
using GLM, which could assume the form:
y<-cbind(sexf, sample-sexf)
model<-glm(y ~ age+month+year, binomial)
summary(model)
Output:
(Dispersion parameter for binomial family taken to be 1)
Null deviance: 8956.7 on 582

Classification error rate increased by bagging - any ideas?
Hi,
I'm analysing some anthropometric data on fifty odd skull bases. We know the
gender of each skull, and we are trying to develop a predictor to identify
the
sex of unknown skulls.
Rpart with cross-validation produces two models - one of which predicts
gender
for Males well, and Females poorly, and the other does the opposite (Females
well, and Males poorly). In both cases the error

Predicting classification error from rpart
Hi,
I think I'm missing something very obvious, but I am missing it, so I
would be very grateful for help. I'm using rpart to analyse data on
skull base morphology, essentially predicting sex from one or several
skull base measurements. The sex of the people whose skulls are being
studied is known, and lives as a factor (M,F) in the data. I want to
get back predictions of gender, and

Help with accessing elements of a list
Hi,
As part of the analysis of a longitudinal study, I have a list, called wg,
on R 1.3.1 for windows created as follows -
wg <- by(xx, xx$mrn, function(xx) lm(xx$maternal.wt ~ xx$gestation,
data=xx))
xx is a data.frame, and so wg contains the results of 293 linear
regressions, as lm objects.
Now what I want is to extract the 293 intercepts and regression coefficients
as a vector, and

Using variable names in for loops - Generating plots semi-automatically from a series of variables Partly solved
Hi,
This code is trying to produce a series of graphics files, with plots
of male and female disease rates by age, one plot per disease. The
dataframe contains a variable 'Age' and a set of variables called
'Male_CVD, Female_CVD,Male_RTA,Female_RTA, and so on. For each
disease, I want to pull out the column of data containing the word
'Male' and plot this against age, and then

Advice on obscuring unique IDs in R
Dear colleagues,
This may be a question with a really obvious answer, but I
can't find it. I have access to a large file with real
medical record identifiers (mixed strings of characters and
numbers) in it. These represent medical events for many
thousands of people. It's important to be able to link
events for the same people.
It's much more important that the real record numbers

Passing the name of a variable to a function

I have a problem which has bitten me occasionally. I often need to
prepare graphs for many variables in a data set, but seldom for all.
or for any large number of sequential or sequentially named variables.
Often I need several graphs for different subsets of the dataset
for a given variable. I run into similar problems with other needs
besides graphing.
