Hello everyone I'm having a little difficulty with R-2.0.0 CMD check. My field is Bayesian calibration of computer models. The problem is that I have a large collection of toy datasets, that in R-1.9.1 were specified with lines like this: x.toy <- 1:6 y.toy <- computer.model(x.toy) z.toy <- reality(x.toy) in file ./data/toys.R ; functions computer.model() and reality() are defined in ./R/calibrator.R. [In this application, the (toy) functions computer.mode...

I tried apt-get install llvm-dev just now, and it says it was already installed, and when I again try compiling toy.cpp, it gives the same set of error messages.

Here are several ways to get there, but your original loop is fine once it is corrected: > for (i in 1:2) smean[i] <- mean(toy$diam[toy$group==i][1:nsel[i]]) > smean [1] 0.271489 1.117015 Using sapply() to hide the loop: > smean <- sapply(1:2, function(x) mean((toy$diam[toy$group==x])[1:nsel[x]])) > smean [1] 0.271489 1.117015 Or use head() > smean <- sapply(1:2, function(x) mean(head(toy$diam[toy$group...

...t from group 1 say "n" rows and calculate the mean; then select "m" rows from group 2 and calculate the mean as well. So far I've been using a for loop for doing it but when it comes to a large data set is rather inefficient. Any hint to vectorize this would be appreciated. toy = data.frame(group = c(rep(1,10),rep(2,8)), diam = c(rnorm(10),rnorm(8))) nsel = c(6,4) smean <- c(0,0) for (i in 1:2) smean[i] <- mean(toy$diam[1:nsel[i]]) Thanks Pedro [[alternative HTML version deleted]]

hi, with LLVM 3.1, i am trying to compile toy.cpp from http://llvm.org/docs/tutorial/LangImpl7.html#code. i got the following error: $ clang++ -g toy.cpp `llvm-config --cppflags --ldflags --libs core jit native` -O3 -o toy toy.cpp:4:10: fatal error: 'llvm/IRBuilder.h' file not found #include "llvm/IRBuilder.h" i fixed thi...

Hi Pedro, This may not be much of an improvement, but it was a challenge. selvec<-as.vector(matrix(c(nsel,unlist(by(toy$diam,toy$group,length))-nsel), ncol=2,byrow=TRUE)) TFvec<-rep(c(TRUE,FALSE),length.out=length(selvec)) toynsel<-rep(TFvec,selvec) by(toy[toynsel,]$diam,toy[toynsel,]$group,mean) Jim On 4/3/16, Pedro Mardones <mardones.p at gmail.com> wrote: > Dear all; > > This must have a r...

...quot;true" data or not, but we'd like to at least do some sensitivity analyses by dropping "trailing zeroes" (ie, when there are non-zero responses for some duration of the data that then "flat line" into all zeroes to the end of the time period) I've included a toy dataset below. Basically, we have the data in the "long" format, and what I'd like to do is subset the data.frame by deleting rows that occur at the end of a person's data that are all zeroes. In a nutshell, select rows from a person that are continuously zero, up to first no...

Dear helpeRs, I have a dataframe (14947 x 27) containing measurements collected every 5 seconds at several different sampling locations. If one measurement at a given location is less than zero on a given day, I would like to delete all measurements from that location on that day. Here is a toy example: toy <- data.frame(CH = rep(3:5,3), DAY = c(rep(4,5), rep(5,4)), SLOPE = c(seq(0.2,0.6, .1),seq(0.2, -0.1, -0.1))) In this example, row 9 has a negative measurement for Chamber 5, so I would like to delete row 6, which is the same Chamber on the same day, but not row 3, which is the...

...LLVM. I noticed that llvm-config --cxxflags includes the -fno-exceptions flag. Do I need to throw no exceptions whatsoever in my application to use LLVM JIT? As a minimal example, I modified the code in https://github.com/llvm-mirror/llvm/tree/master/examples/Kaleidoscope/BuildingAJIT/Chapter2. In toy.cpp, I update LogError to throw an exception: std::unique_ptr<ExprAST> LogError(const char *Str) { fprintf(stderr, "Error: %s\n", Str); throw std::runtime_error(""); } and I catch that exception in MainLoop: static void MainLoop() { while (true) { fprintf(stde...

I don't know if the toy program in chapter 4 of the tutorial implementing Kaleidoscope in llvm with C++ is part of your regression suite, but with the version of llvm I installed last weekend, it does not compile: hendrik at lovesong:~/dv/llvm/tut$ g++ -g toy.cpp `llvm-config --cppflags --ldflags --libs core jit native`...

Hello , I have build llvm from release_38 branch ( only llvm and clang ) and install it. My DYLD_LIBRARY_PATH points to installation-directory/lib. I am compiling example files for Kaleidoscope with following command : clang++ -g toy.cpp -std=c++11 `llvm-config --cxxflags --ldflags --system-libs --libs core mcjit native` -O3 -o toy but it fails with following error: Undefined symbols for architecture x86_64: "llvm::CmpInst::CmpInst(llvm::Type*, llvm::Instruction::OtherOps, llvm::CmpInst::Predicate, llvm::Value*, llvm::V...

...ne knows what (or how to find out what) the actual command to compile Kaleidoscope is? I followed cmake/nmake down through maybe half a dozen levels before getting lost, so I tried to develop a compiler invocation from scratch. I got as far as cl /EHsc /I\d\llvm-2.6\include /I\llvm\include /wd4355 toy.cpp which successfully generated toy.obj and spat out 86 link time error messages -- as expected, it needs the libraries specified. cmakelists.txt says set(LLVM_LINK_COMPONENTS core jit interpreter native) so I made a guess at the .lib file corresponding to the first of these, and tried cl /EHsc...

Dear all, I want to expand only one of variable in data frame and the others variable will be following with the expand variable. Here my toy example: toy.df <- data.frame(size=c(3,1,2,0,3,5,1,0), group=LETTERS[1:8], country=c("Germany","England","Argentina","Mexico","Italy","Brazil","France","Spain"), w=rep(0,8), d=rep(0,8), l=rep(0...

Hello all, I am trying to build the kaleidoscope sample code on Mac os (10.6). What I have done to get llvm libraries : 1) Downloaded llvm-2.6 source code 2) ./configure 3)make 4) make intall Then I tried to build kaleidoscope as described in the tutorial: g++ -g -O3 toy.cpp `llvm-config --cppflags --ldflags --libs core` -o toy I get typical link time errors (undefined symbols: ...) as if the linked libraries were not found ( llvm-config seems to work fine) The very first errors are the following: ld: warning: in /usr/local/lib/libLLVMCore.a, file was built for...

...conditions: (a) I only want the levelplot to appear (I don't want axes, colour key, etc) in the viewport and (b) I want the levelplot to expand to the maximum allowable space in the viewport while observing the aspect ratio of the plot. Condition (a) is OK, but (b) is giving me trouble. A toy example is: library(lattice) library(grid) x <- 1:10 y <- 1:10 grid <- expand.grid(x=x, y=y) grid$z <- grid$x*grid$y asp.ratio.1 <- 2 asp.ratio.2 <- .5 asp.ratio.3 <- 1 test.1 <- levelplot(z~x*y, grid, cuts = 5, xlab="", axes = FALSE, aspec...

...as documented in [1]. Right now we don't test this feature **at all** and as a result it has been or is * broken in trunk * broken by those packaging LLVM * broken in the official release binaries I'd like to propose a few ideas I have to improve this situation. I've created a small toy project [2] that uses the exported LLVM CMake targets. What I'd like to happen is for this project to become part of the LLVM source tree (or as a sub project) so that it can be tested in various scenarios. I do not want this toy project to be a maintenance burden so it makes very minimal use o...
