similar to: square and points on the same figure

Hi, I have the following code to randomly generate the points: csr <-function(n=60){ x=runif(n) y=runif(n) f=cbind(x,y) } plot(csr()) I wonder how to code to make the first twenty points to be BLUE; second twenty points to be RED; the last twenty points to be GREEN? Thanks, Sam --------------------------------- [[alternative HTML version deleted]]

Hi, I am new to R. I don't have strong background of statistics. I am a student of Geotechnical Engineering. I tried to run a nonlinear regression for a three-variable function, that is N = f(CSR, ev) # N is a function of CSR and ev, and N = CSR/(A +B*CSR), wherer (A,B) are function of ev. N, CSR and ev are observed in the experiments. Following is my R script. rm(list=ls())

Hi everyone, I'm stuck on my dissertation which is due next week. I'm a business major student and my project is a comparative research on corporate social responsibility (CSR) between Chinese and German firms. According to my literature review, it's quite obvious that German firms have much better CSR initiatives and strategies than the Chinese ones and I wanted to test whether it was

I would like to add a class to the SparseM package. I have a class "matrix.csr" that describes a matrix in compressed sparse row format, now I would like a class matrix.diag.csr that describes such objects when they happen to be diagonal. The idea is that matrix.diag.csr objects should behave (later in life) exactly like matrix.csr objects, the distinction is only needed in order to

I'm trying to resolve a small problem that has arisen from introducing a NAMESPACE for the package SparseM. Prior to the namespace I had a class "matrix.diag.csr" that consisted of diagonal sparse matrices. It was defined to have the same attributes as the matrix.csr class and setAs was used to define how to coerce integers and vectors into this form:

Hello, I would like to read and write sparse matrices using the functions write.matrix.csr() and read.matrix.csr() of the package e1071. Writing is OK but reading back the matrix fails: x <- rnorm(100) m <- matrix(x, 10) m[m < 0.5] <- 0 m.csr <- as.matrix.csr(m) write.matrix.csr(m, "sparse.dat") read.matrix("sparse.dat") Error in initialize(value, ...)

I'm working on lldb. I've just submitted a very small change (r217229) to Triple.h/.cpp. Soon after I get a mail subject: buildbot failure in LLVM on lld-x86_64-darwin13 Details: http://lab.llvm.org:8011/builders/lld-x86_64-darwin13/builds/2571 Blamelist: mg11 My small change certainly did not cause lldb's build to fail on my machine. I looked into the build-log:

In the last few days I've received couple of messages pointing out that our SparseM package fails to install on the patched version of 1.7.0. Laurent Gaultier kindly suggested that replacing: setGeneric("as.matrix.csr") by setGeneric("as.matrix.csr", function(x, nrow, ncol, eps) standardGeneric("as.matrix.csr")) was sufficient to fix the problem.

Hi Fred, Thanks. How did you get to " The build log show this error: /Users/buildslave/as-bldslv9/lld-x86_64-darwin13/llvm.src/lib/Target/ARM/MCTargetDesc/ARMMCTargetDesc.cpp:92:11: error: enumeration values 'KalimbaSubArch_v3', 'KalimbaSubArch_v4', and 'KalimbaSubArch_v5' not handled in switch [-Werror,-Wswitch] switch (triple.getSubArch()) { " from here

Hello LLVMdev!! Yesterday I posted a patch request to the llvm-commits list requesting that someone could apply a patch to Triple.h and Triple.cpp for me. I didn't get any response so I wondered whether I should have posted to this list instead. My story is as follows: we are trying to get lldb/llvm support for CSRs range of Kalimba DSPs. Eventually we are planning to hire someone to

Hi, We have some DSP architectures (kalimba) which have 24-bits as their "minimum addressable unit". So this means that the sizeof a char (and an int and a short for that matter) is 24-bits. I quickly read the posted link WritingAnLLVMBackend.html but did not see an obvious answer to the following question: Is it possible to write a backend that faithfully represents these

When compiling C code below for AArach64, I saw that shrink-wrapping didn't happen due to the very early uses of CSRs in the entry block. So CSR spills/reloads are executed even when the early exit block is taken. int getI(int i); int foo(int *P, int i) { if (i>0) return P[i]; i = getI(i); return P[i]; } It's not that hard to find such cases where

Hi Johnny, Thanks for this - particularly the tip about cfe-dev. I'm currently trying to coerce lldb to debug these type of architectures (our current toolchain already outputs good dwarf info). However, I'm struggling since lldb has just assumes that the size of a byte is universally 8-bits. At some stage, I *think* at some stage we'd like to derive a compiler, from the "same

I looked on the openssl man page but am too dense with commands to understand what I need to do..... Ran into problems generating a key and CSR for SSL, because the web site is on a server with an old Ensim Control Panel. Please someone knowledgeable, give me the openssl commands I need to use, after I ssh into the web site, to generate a 2048 bit key and csr. TIA and Happy New Year!
