dealing with a messy dataset
dear R-users,
I am facing a quite regular and basic problem when it comes to dealing
with datasets, but I cannot find any satisfying answer so far.
I have a messy dataset of galaxies like that :

logit model interpretation
Hello everyone
I appologize for my lack of experience in statistical methods. I am an R
user begginer and I am running a logit model using "zelig" and "pcse"
packages. I will go to the point and is that Im having problems with
interpreting the results of my models.. It is really simple (I guess for the
most advanced scholars) however I really dont understand how to interpret

[LLVMdev] pb05 benchmarks for llvm/dragonegg 3.2
Duncan,
With the commit from http://lists.cs.uiuc.edu/pipermail/llvm-commits/Week-of-Mon-20121203/158488.html,
the Polyhedron 2005 benchmarks complete again on x86_64-apple-darwin12. The result are similar to what
were seen with FSF gcc 4.6.2svn and llvm/dragonegg 3.0 (which was the last release that passed pb05)

Creating list or numeric vectors out of selected columns of row oriented data
I am just assuming this can be done, but I have not gotten close to
making it happen. I have a data file with about 1 million rows with
1470 unique subjects. Each row represents a small set of observations
made on a specific date for a single subject. I would like to
transform the data so that I have an R object with a single entry for
each subject and start date and vectors for the

I would like to transfer some Splus functions in R.
But I have a problem first about this assignation in Splus :

I am a bad programmer : I don't understand the R help
How to modify these functions ?
Thank you very much for your help

testing non-linear component in mgcv:gam
Hi,
I need further help with my GAMs. Most models I test are very
obviously non-linear. Yet, to be on the safe side, I report the
significance of the smooth (default output of mgcv's summary.gam) and
confirm it deviates significantly from linearity.
I do the latter by fitting a second model where the same predictor is
entered without the s(), and then use anova.gam to compare the

dealing with a messy dataset
Is this a fixed width format?
If so, read.fwf() in base, or read_fwf() in the readr package will solve the problem. You may need to trim trailing spaces though.

Input file format to Anova from car package

My question is related to input file format to an Anova from car package.
Here is an example of what I did:
My file format is like this (and I dislike the idea that I will need
to recode it):

str() with attr(*, "names") is extremely slow for long vectors
Hi,
I noticed some time ago that, for instance, named vectors that are
really makes str() really slow when displaying the names attribute. I
don't know exactly when this started, but it wasn't the case say 1-2
years ago. Example (on a WinXP 1.8GHz):
> s <- 1:1000; names(s) <- s
> system.time(str(s))
Named int [1:1000] 1 2 3 4 5 6 7 8 9 10 ...

I have been struggling with this model for some time now and I just can't

[RFC] Delaying phi-to-select transformation until later in the pass pipeline
Summary
=======
I'm planning on adjusting SimplifyCFG so that it doesn't turn two-entry phi
nodes into selects until later in the pass pipeline, to give passes which can
understand phis but not selects more opportunity to optimize. The thing I'm
trying to do which made me think of doing this is described below, but from the
benchmarking I've done it looks like this is overall a

Puzzled at lm() and time-series
I tried toy problems and there doesn't seem to be a basic problem
between lm() and ts objects:
X = data.frame(x=c(1,2,7,9), y=c(7,2,3,1))
lm(y ~ x, X)
X <- lapply(X, function(x) ts(x, frequency=12, start=c(1994,7)))
lm(y ~ x, X)
and this works fine - whether you do an lm() before or after making ts
objects, it's okay.
But I have a situation where things aren't okay.

Bayesian estimate of prevalence with an imperfect test
Hi all!
I'm new to this forum so please excuse me if I don't conform perfectly to
the protocols on this board!
I'm trying to get an estimate of true prevalence based upon results from an
imperfect test. I have various estimates of se/sp which could inform my
priors (at least upper and lower limits even if with a uniform distribution)
and found the following code on this website..
