similar to: [LLVMdev] Forward: Discussion about custom memory allocators for STL

Hi Chris, Thanks a lot for a detailed opinion and explanation! It really answers the original question, without going to far into political discussions about boost and generic allocators pros/cons aspects. ----- Ursprüngliche Mail ---- > Von: Chris Lattner <sabre at nondot.org> > An: LLVM Developers Mailing List <llvmdev at cs.uiuc.edu> > Gesendet: Sonntag, den 18.

Hello, I was looking at how the memory for MachineBasicBlocks is managed and something seems strange. On one hand, a MachineFunction uses a recycling allocator to create and destroy MBBs without costly heap allocation (the same is done for MachineInstrs, MachineOperands, etc.). On the other hand, each MBB also has a number of STL vectors within it. For example, for Predecessors, Successors,

Hi All, I am in the process of writing an R extension in c++ and am using several STL containers (e.g., vector<double>, map<int, double>, multimap<int, double>). I make sure to clear all these containers at the end of the .Call. Everything compiles and runs just fine, but I'm a bit worried since I haven't found any other packages that use STL. So, my question: is it

Hola LLVMers, We saw a problem with some code in LiveIntervalAnalysis.h/.c which we've fixed locally. We'd like to get a patch to the mainline and want to know how you'd like it fixed. A couple of things come together to cause the problem: struct Idx2MBBCompare { bool operator()(const IdxMBBPair &LHS, const IdxMBBPair &RHS) const { return LHS.first <

I am trying to understand the nuances of STL (seasonal trend decomposition with loess) based on William Cleveland's (and others?) original development. I do not understand the specification or use of "frequency components" or equivalent "low-pass filter" components in the stl() function. I have run the stl() function on a standard example data (co2) in both S-Plus and

Hi everyone. I'm having some troubles with STL function to decompose some data. My issue is that I have monthly data from September 2005 up to August 2010 i. e. 60 observations. I define it in the following way: *u<-read.csv("C:/CELEBREX.csv",header = TRUE) u.ts<-ts(u, start=c(2005,9), frequency=12) * The issue is that when I try to use stl(u.ts, 'per') Then the

Hi, I have a monthly time series with missing values and I would use stl function to identify seasonality. I tried all settings of na.action but the result is the same: stl(tm245,s.window=11, na.action=na.pass) Error in stl(tm245, s.window = 11, na.action = na.pass) : NA/NaN/Inf in foreign function call (arg 1) Can you help me? Thanks Andrea Toreti [[alternative HTML version

I am running R 1.2.2 under Linux. When using the function stl in the ts library, how can I save the seasonal component? What I would like was something like: library(ts) data(nottem) data.stl <- stl(nottem, "per") x <- data.stl$sea This what I get: > x NULL I would, however, like to store in x the seasonal component. Thanks in advance. Francisco. -- Francisco

I don't understand the output of stl. As a simple example: y <- numeric(1:365) y[250] = 1 stl <- stl(ts(y, frequency=7), s.window="periodic") This returns without error but the results are puzzling to me. If you plot the results it is probably easiest to visualize what I mean. plot(stl) This shows the original data (a single spike at 250). A trend (which also shows a bump

G'day, I am looking at monthly reports, and have three series of monthly data from 2007 to 2009. I would like to show the season decomposition of these two series side by side on the one device, however using plot doesn't seem to respect any use of layout(matrix(1:3, ncol=3)) or par(mfcol=c(1,3)). I'm guessing that this means that the plot(stl) perhaps uses them, but I can't find

Dear helpeRs, Is it possible to change the shading colour of the range bars in the plot generated by plot.stl? By default they are grey, but I would prefer them white (I am preparing some graphics for a powerpoint presentation so I'm inverting all colours). As far as I can see plot.stl allows you to turn off the range bars, but nothing about the shading colour. I tried to look at the
