similar to: Confidence intervals in Ripley's K function - a little challenge...

I normally use the following code to create a figure displaying the mark correlation function for the point pattern process "A": M<-markcorr(A) plot(M) I have now started to use the following code to perform 1000 Monte Carlo simulations of Complete Spatial Randomness (CSR). It is a Monte Carlo test based on envelopes of the Mark correlation function obtained from simulated point

Dear All, I have a collections of spatial data. I have to analyze pairs of these point patterns to test their spatial interaction. I was moving towards the cross K Ripley's function. The problem, however, are the following: 1) What is the best way to get a single real value that represents the interaction "power"? 2) How to obtain a value that even allows me to rank the pairwise

Hi--I'm trying to run a Ripley's K analysis on a point pattern within a window of 1 square km. The maximum distance I want to use is the diagonal of the window, around 1400m, run in 50m increments. The function defaults to a 250m maximum--I thought this was simply the way I had plotted it, but when I exported the data there was nothing over 250m. I've looked into seq and ginterval,

Dear friends, I am studying the spatial distribution of trees in a tropical swamp forest in Brazil, and the spatial association between the trees and other forest and non forest elements. These are point pattern analysis of mapped data, preferentially done with the L function of Ripley. I have recently discovererd the R-project and would like to know whether it is possible to do these

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:

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

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())

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, ...)

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

Dear all, I'm training an SVM with default settings on a matrix csr (SparseM package). I realized that if I train the SVM with the (hopefully) equivalent matrix (Matrix package) representation, the returned models and predictions sometimes differ. I expected both representations of the same data to lead to the same results though. It could be that it is a scaling problem, because unscaled

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:

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

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 all, I want to transform a dCgMatrix from package Matrix into a matrix.csr from package SparseM, and I found out this link : http://stat.ethz.ch/R-manual/R-devel/library/Matrix/html/SparseM-conv.html But there's no informaion about usage/description/arguments, so how do I use this SparseM-conversions method ?? Is it a function ?? By the way I already tried function: as.spam.matrix.csr

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
