Strange behaviour of as.Date function
Dear All,
I'm happily extracting data of temperature from an oracle db
under R via RODBC. After manipulating the extracted data I put them

Likelihood optimization numerically
Dear List,
I am not sure how should i optimize a log-likelihood numerically:
Here is a Text book example from Statistical Inference by George Casella, 2nd
Edition Casella and Berger, Roger L. Berger (2002, pp. 355, ex. 7.4 # 7.2.b):
data = x = c(20.0, 23.9, 20.9, 23.8, 25.0, 24.0, 21.7, 23.8, 22.8, 23.1, 23.1, 23.5, 23.0, 23.0)

how to handle irregularly spaced data as timeseries
I have a set of modeled climate data recorded at irregular intervals.
The format of the data is such that there are monthly measurements for
the years 2000, 2020, 2050, 2080, etc. Therefore I have 12 regular
records, a skip of some number of years, then 12 more monthly records,
another skip, and so on.... I created a dataframe from .txt with the

robust method to obtain a correlation coeff?

Being a R-newbie I am wondering how to calculate a correlation

data format issue
Dear all-
I have a dataset (see a sample below - but the whole dataset is June
2005 - June 2008). The "LST" format is "YYMMDDHHmm" and I would like to
get the hourly average of the "mph" for the summer months (spanning all
years). I have been trying to use "aggregate" but am not having much
success at all! any thoughts would be greatly appreciated.

I don't know either. Perhaps someone else on the list who uses that _contributed_ package will know.
Please be aware that it is both possible and preferred that you make reproducible examples so others can troubleshoot. See any of [1][2][3]

Panel-specific colours in barchart, lattice package.
I would like, for possibly invalid reasons, to have the bars of the

from panel

I've read the help as much as I am capable of, and done an RSiteSearch

becoming any wiser.

Error in `[[<-.data.frame`(`*tmp*`, alt.name, value = integer(0)) with mlogit
Hello,
There's a typo in your call to mlogit.data, it should be
alt.var="nbChev", not alt.var="noChev".
Then the error is different. You should check the call arguments to see
if they make sense.
Hope this helps,

Who wants faster LLVM/Clang builds?
Hi,
Recently I've done some experiments on the LLVM/Clang code and discovered that many of our source files often include unnecessary header files. I wrote a simple tool that eliminates redundant includes and estimates benefits of doing it, and the results were quite nice: for some files we were able to save 90% of compile time! I think we want to apply some of the cleanups I found, but
