Hi, I am new to R and I want to know how to use C code which contains two functions one called inside another.I know that how to use C code in R if it has only one function but dont know how to do it in above case. I want to use the same in R .My C code is as follows. //#include <R.h> void sayHello(); void g(); void sayhello() { Rprintf("Hello world %d\n",global); } void

Hi, I am new to R and I want to plot points on the Map of New York . I also want to divide map of New York into small grids(not fixed) .I want that these point should be plotted from a file.How can I do it?Any help would be greatly appreciated. Thanks Jaimin [[alternative HTML version deleted]]

I am new to R.I want to draw grid from a csv file which contains latitude minimum ,latitude maximum ,longitude minimum ,longitude maximum.The grid should be divided into exactly 4 quadrants. The map is of NY state of USA. I want to know how can I do it. Help would be appreciated. Thanks Jaimin [[alternative HTML version deleted]]

Hello Everyone, I am new to R and would like to create a quad tree in R. However the problem is that I don't think R has pointers. Is there any way to create a tree in R? Thanks [[alternative HTML version deleted]]

Hi , I have a function which passes a vector from R to C. However the size of the vector is decided inside the c program. But as I have to pass the size while calling the function from R lot of my space is getting wasted. Is there any other alternative? I call c function as :

After considerable experimentation I'm forced to accept that Samba 3 has problems with the combination of being a domain member, the 2.6 kernel, and Dell 2850 hardware. It works fine on the 2.4 kernels but fails on all the 2.6 versions I have avaialble for testing. I have one machine that I really prefer could stay at 2.6 so my last resort there is to try a downgrade to samba 2.X In the

Hi As the title says, are all the debug nodes of LLVM IR avaialble in DWARF? If I add a new custom MDNode in LLVM IR, can I expect the debug data will be available in DWARF in the binary if I compile in debug mode?

Hi, I am using a function which accepts the string from R and prints it. But when I am calling .C("main","hello"); it is printing any random thing. My C function is void main(char *str) { Rprintf("%s",str); } Can you help how to achieve this using .C interface? Thanks Jaimin [[alternative HTML version deleted]]

For cost reasons, I'd like to replace SAS on my PC under Win XP Pro. Nearly all my work involves medium-size datasets (100k-10M) records which I cleanup, relate, fliter and get into shape for analysis using SAS/SQL followed by standard statistical procedures, e.g. regression using SAS proc reg. It seems to me that this type of analysis could be done in MySQL followed by R, but I'd like

Hi all, Say I have a matrix A with dimension m x 2 and matrix B with dimension n x 2. I would like to find the row in A that is closest to the each row in B. Here's an example (using a loop): set.seed(1) A <- matrix(runif(12), 6, 2) # 6 x 2 B <- matrix(runif(6), 3, 2) # 3 x 2 m <- vector("numeric", nrow(B)) for(j in 1:nrow(B)) { d <- (A[, 1] - B[j, 1])^2 + (A[,

Hi, David, Thank you very much for getting back to me! Sorry about the messy code example. I am re-posting here (including the error message): > example.3=data.frame(levels=as.numeric(XXX[,c(4)]),replicate=rep(c("0","1","2","3","4","5"),3),conditions=c(rep("11",6),rep("12",6),rep("13",6)))> example.3? ?

Hi Everyone, I have csv file which is in following format xmin,xmax,ymin,ymax,zmin,zmax I want to plot 3d graph with all the all octants being displayed as well. Any idea? I have used scatterplot3d package but it does not seem to have anything by which i can draw "octants" inside cube as well. Thanks [[alternative HTML version deleted]]

Hi Everyone, I am new to R and I am trying to return array(dynamic) from C to R. But when I print array(vector) in R it gives NA as output. When I print array in C it gives correct o/p but some how it is not returned to R. *Code in C:* void test(double *vec,double *size){ vec = (double *)calloc(2 , sizeof(double)); *(vec+0) = 1; *(vec+1) = 2; *size = 2; } *Code in R:*

Hi, The question is as follows: has anyone coded panel data unit root tests with R? Even the "first generation" tests (see e.g. Levin & Lin 1993; Pesaran, & Smith & Im 1996; Maddala & Wu 1999) would be sufficient for my needs. To my understanding, these are rather easy to code, but as I have taken just my first steps in coding with R, existing code would save me

Hello All, I'm looking to test a variable in a logit model (glm(..., binomial(link="logit"))) for exogeneity (endogeneity). At this point I am planning to try implementing Jeffery Grogger's "A Simple Test for Exogeneity in Probit, Logit, and Poisson Regression Models", Economic Letters, 1990. To do this, I need to be able to do an instrumental variables NLS

Dear R users. I have data observed on the surface of a torus, and am trying to fit the nonlinear regression using the geodesic equation on a torus. Could anyone give me a helpful advise on this problem? I would definitely appreicate your reply. Sincerely, SUNGSU KIM [[alternative HTML version deleted]]
