Hey,
I'm trying to build something like this

The code runs well if I use the same csv files as the author, but with mine

merging data frames gives all NAs
Dear kind R helpers,
I have a vector of runway names in rwy ("31R", "31L",... the number is
user selectable)
arrgnd is a data frame with data for all flights and all runways, with a
Runway column.
I am trying to subset arrgnd into a dat frame for each selected runway,
and then combine them back together using the following code:
for (j in 1:nr) { # nr = number of

How to select a row from one dataframe that is "close" to a row in another dataframe
I have two data frames of flight data, but they have very different
numbers of rows. They come from different sources, so the data are not
identical.

[3] "MkdFltNbr" "DprtTrpnStnCd"

CRAN mirror for R in India: new one at WBUT, how do we get listed in the CRAN website?
Dear All,
Folks at the West Bengal University of Technology has set up a mirror to
distribute R and associated packages. Here is the URL:
http://mirror.wbut.ac.in/CRAN
This will be helpful for R users in South Asia and the adjoining countries.
I have yet to see the site featured in the CRAN list of mirrors. What needs
to be done? For those of you who are impatient and would like to give it a

How to do a time-stratified case-crossover analysis for air pollution data?
Dear Experts,
I am trying to do a time-stratified case-crossover analysis on air
pollution data and number of myocardial infarctions. In order to avoid
model selection bias, I started with a simple simulation.
I'm still not sure if my simulation is right. But the results I get from
the "ts-case-crossover" are much more variable than those from a glm.
Is this:

[LLVMdev] trunk's optimizer generates slower code than 3.5
The regressions in the performance of generated code, introduced
by the llvm 3.6 release, don't seem to be limited to this 8 queens
puzzle" solver test case. See...
http://www.phoronix.com/scan.php?page=article&item=llvm-clang-3.5-3.6-rc1&num=1
where a bit hit in the performance of the Sparse Matrix Multiply test
of the SciMark v2.0 benchmark was observed as well as others.

[LLVMdev] trunk's optimizer generates slower code than 3.5
Using the SciMark 2.0 code from

I am able to reproduce the 22% performance regression in the run time
of the Sparse matmult benchmark.
For 10 runs of the scimark2 benechmark, I get 998.439+/-0.4828 with
the release llvm clang 3.5.1 compiler

[LLVMdev] trunk's optimizer generates slower code than 3.5
I submitted the problem report to clang's bugzilla but no one seems to
care so I have to send it to the mailing list.
clang 3.7 svn (trunk 229055 as the time I was to report this problem)
generates slower code than 3.5 (Apple LLVM version 6.0
(clang-600.0.56) (based on LLVM 3.5svn)) for the following code.
It is a "8 queens puzzle" solver written as an educational example. As
