[LLVMdev] possible bug in COFFObjectFile::getSymbolType()
...s llvm/test/MC/ARM/Windows/mov32t-range.s to fail, because the symbol "truncation" comes back as SymbolRef::ST_Data, and the code gets dumped as bytes instead of disassembled. I traced the problem back to COFFObjectFile::getSymbolType() in llvm/lib/Object/COFFObjectFile.cpp : if (Characteristics & COFF::IMAGE_SCN_MEM_READ && ~Characteristics & COFF::IMAGE_SCN_MEM_WRITE) // Read only. Result = SymbolRef::ST_Data; I think it should also check for ~Characteristics & COFF::IMAGE_SCN_MEM_EXECUTE. The symbol, in this case, is READ, EXECUTE, !WRITE....

[LLVMdev] possible bug in COFFObjectFile::getSymbolType()

transparent concentric circles
I have a data set which I would like to plot as a set of concentric circles. The data represent a count of the number of characteristics shared by various elements - an example would look like this: 1 100 2 75 3 50 4 25 I.e. all four sets share 25 characteristics, three of them share 50 characteristics, and so on. I would like to plot these as concentric circles, with the circle size preferentially being proportional to the size...

fft: characteristic function to distribution
The characteristic function is the inverse Fourier transform of the distribution function. The characteristic function of a normaly distributed random variable is exp(-t^2/2). x=seq(-2,2,length=100) fft(pnorm(x),inverse=T)/length(x) exp(-x^2/2) Why aren't the inverse fft and the mentioned function the same? Tha...

rsync, excluding files w/certain characteristics
hey, I was wondering - is there an option to rsync which allows you to exclude transfers of files with a certain size or other characteristics? I want to setup a 'partial' rsync mirror where I only pull files under 5M, for example.. I see the option for including/excluding file names in the usage, but not file sizes.. Ed

multiple comparisons and generalized least squares
...per provenance, 10 leaves/fruits/seeds per tree). Provenances are fixed effects (they were not randomly chosen), but trees within provenances and leaves/fruits/seeds within trees were randomly assigned. I wanted to check whether there were any between-provenance differences concerning the measured characteristics. For the leaves, fruits and seeds datasets, I tried some lme models of the form: model<- lme(characteristic~1, random=~1|tree, data=leaves) model<- lme(characteristic~provenance, random=~1|tree, data=leaves) or, in case of heteroscedasticity on the provenance level: model<-lme(char...

subsetting like in SAS
Hi, Being in the process of translating some of my SAS programs to R, I encountered one difficulty. I have a solution, but it is not elegant (and not pleasant to implement). I have a large dataset with many variables needed to identify the origin of a sample, many to describe sample characteristics, others to describe site characteristics. I want only a (shorter) list of sites and their characteristics. If "origin", "ship_cat", "ship_nb", "trip" and "set" are needed to identify a site, in SAS you'd sort on those variables, then read t...

fft: from characteristic funtion to density function
Hello all! I've posted the question before but I am still struggling for an answer, please help if you can;-) Suppose a discrete series of data is generated by the following equation: CF=exp(-(t^2)/2) which is the characteristic function of a random variable X with standard normal distribution, how do I *numerically* solve for its probability density function? i.e., obtain a series of data that plots a well know bell-shape curve? Or, find x such that Pr(X<x)=0.05? I have no problem to derive the forward and inverse Fou...

Tabulating Baseline Characteristics on specific observations
I have a data set with many missing observations. When I run a regression, R of course discards the observations (the whole row) that have "NA". I want to tabulate some baseline characteristics (column means) but only for the observations that R used for the regression. I tried to recreate this data frame by using na.omit on the original data frame, but this will not work as this will discard an observation with an "NA" in any column, and not just in the covariates. In summary...

Local channel characteristics
...ions. One fancy idea came up: if my generic dial plan uses Dial() with no timeout, can I assign it a timeout for special purposes by Dial(Local/some-exten@mycontext,,20) or even add other Dial() options. Well, I can't. (Maybe a feature request?) So this pseudo channel seems to lack some characteristics of a "real" one. Now the question is: what characteristics Local does have? I can imagine that many Dial() options won't be effective, either. Where are these stuff documented? Yuan Liu

This may be child's play for many on this list, but how do I transform this data file to two columns, one called "id"...

Dynamically switching lattice device characteristics in Sweave under Makefile control

If you look in the Makefile you will see that there is a fooD.tex and a fooH.tex file controlling whether the display or the other one (I forget why I called it H) is active. That is how I control the beamer stuff. The problem for me is that the device characteristics need to be controlled in the individual .Rnw files Should you be inclined to read the content of the slides (and do bear in mind that they are a work in progress, to be presented on Sunday) I will tell you I am particularly proud of the slide entitled "Definition of linear mixed-effects mode...

How to check if a value of a variable is in a list
Hi all, I am working with some social network analysis in R and ran into a problem I just cannot solve. Each observation in my data consists of a respondent, some characteristics and up to five friends. The problem is that all of these five friends might no show up later as a respondent (observation). Therefore I might not have characteristics on all the friends listed in the data and I want to restrict my data to only those friends that I also have as respondents. The dat...

item characteristic curves (logistic regression w. constant)
I'm trying to do a sort of home-brew item-characteristic-curve. This is a plot of the probability of getting a test item correct, as a function of the mean score on the test. (The last part is the home brew part.) Logistic regression with glm would work nicely, EXCEPT for the fact that the curve requires a guessing parameter. So the asymptote on the l...
