I have a function for plotting soil texture that I am having a problem with. The function is: plot.psd <- function(sand, clay, ...) { conv.ter <- function(x, y) { x.con <- 100 - x - y*cos(1/3*pi) y.con <- y*sin(1/3*pi) data.frame(x=x.con, y=y.con) } plot(conv.ter(sand, clay), xlim = c(0,100), ylim = c(0,100*sin(1/3*pi)), axes = FALSE, xlab="",

Hi everyone! I'm trying to lear how to call external C code in R but even the R help web-page example is drive me crazy. I copy-paste the example at: http://stat.ethz.ch/R-manual/R-patched/doc/manual/R-exts.html#Interface%20functions%20.C%20and%20.Fortran here is the example: void convolve(double *a, int *na, double *b, int *nb, double *ab) { int i, j, nab = *na + *nb - 1; for(i = 0;

Long story short, my cat jumped on my server at my house crashing two drives at the same time. It was a 7 drive raidz (next time ill do raidz2). The server crashed complaining about a drive failure, so i rebooted into single user mode not realizing that two drives failed. I put in a new 500g replacement and had zfs start a replace operation which failed at about 2% because there was two broken

Dear sir\madam! I'm trying to speed up my R code by writing quite simple dll's in C. But I faced some problems, and I cannot determine their source. #include <Rinternals.h> SEXP mycombin(SEXP N, SEXP k){ int i, *j, *l, c; j = INTEGER(k);l = INTEGER(N); c = 1; if(j[0] > 0 && j[0] < l[0]){ if(j[0] <= l[0] - j[0]){ for(i =

Hi, We recently found a testcase showing that simplifications in instcombine sometimes change the instruction without reducing the instruction cost, but causing problems in TwoAddressInstruction pass. And it looks like the problem is generic and other simplification may have the same issue. I want to get some ideas about what is the best way to fix such kind of problem. The testcase:

From: Jean-Christian de Rivaz <jc at eclis.ch> I suspect that some instructions about how to use the diag/mbr was not updated when the source file was renamed to handoff.S. Here is a simple proposition to fix that.

Hello, everybody, I met a big problem. What I want is to use c code in R. I have load a test code "conv.c" in R and run it successfully. However, in my real code, I use matlab c library (Matrix Inverse function). After I use command "R CMD SHLIB" to share library, I can not use "dyn.load" to load the object in R. "undefined symbol:

...that none of the options yield the expected results for the input code (see below). Except for the indirect case, the function signature is changed to take each structure element. How can I modify LLVM to pass structures by value?

Consider the following C code: typedef __attribute__(( ext_vector_type(2) )) float float2; typedef __attribute__(( ext_vector_type(2) )) __attribute__(( aligned(4) )) float float2_align2; void foo(void) { const float * p; size_t offset; float2 tmp = *((float2_align2 *)(p+offset)); } When compiled with clang ‹emit-llvm I get: define void @foo() { entry: %p = alloca float*, align 4

A majority of my data makes a kriged map perfectly using an exponential model for the semivariogram to fit my data and then going through the commands variofit() to define the model and then krige.conv() to use the model to predict values in a grid. But?one set of my data appears to be linearly correlated for the first 5000 meters and not correlated beyond that. I have been having problems

Hi All, I'm trying to split my dataset, into multiple datasets that i'll analyse later, i wanted to do this dynamically as i might need to rerun the code later. I was looking at doing this via a loop, (Are other methods more appropriate? Would a function be better?) However i'm not sure in R how do do string replacement within the loop in order to create unique dataset names based on

Hi, Can you please help me with this please? What I am trying to do is call a vector from R function and used in the new function So I create 4 functions with these arguments M11 <- function(TrainData,TestData,mdat,nsam) { ls <- list() I have few statments one of them is vectx <- c(,1,2,3,4,5,6,6) vectz <- c(12,34,5,6,78,9,90) and then................ ls(vectx=vtecx,vectz=vectz)
