Hello, I can't link a c code with Mathlib according to introduction of R manual "Writing R Extensions", page 60. It is written : "It is possible to build Mathlib, the R set of mathematical functions documented in 'Rmath.h?, as a standalone library 'libRmath? under Unix and Windows. (This includes the functions documented in Section 5.7 [Numerical analysis

Hello, everybody, Happy New Year! I am a graduate student from Concordia University. I meet a problem when I am working on my thesis. I hope I will get help from you. I have a mathematical model which was already implemented by using R language. However, part of this model includes fixed point iteration algorithm and calculation of large linear equations which n will get to 5000. Because of

Hello, all, I have the same question as the last mail I sent. I have installed libRmath in my system. But I still can not link Rmath through -lRmath. The whole process is as follow.Is there anybody who is so kind to help me find out the problem? I will appreciate very much.

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:

hello, I have a c code which uses clapack. I want to integrate R with this code. It said that I create a R package including my c code. Then build it with putting PKG_LIBS = $(LAPACK_LIBS). I want to know the interface LAPACK_LIBS is Fortran or C? If it is written in Fortran, how can I build them together? If I can build them together, I still use the function in cLapack or the function in

hello, everybody, I met a problem that I want to generate a random uniform number by using function with c interface. What I found is only "unif_rand()", but its range is [0,1]. How can I create a uniform random variable by using a function with c interface. Who can tell me what function it is and how to use? I will appreciate for it very much. Thanks in advance! xiaotong wang

hello, I create a package which includes C code and Lapack. But when I run " R CMD check ". an error message, "/usr/bin/ld: cannot find -lfrtbegin " occurs. could you tell me what is the problem? the detailed message is as follows: [credsim@confsys ~/src]$ R CMD check var * checking for working latex ...

Dear R-Users, I want to ask a question for a colleague of mine. He wants to put a character vector and a numeric vector into one matrix and still have the old character and numeric type for the respective columns. Unfortunately, I am just starting using R and I could not help him. Is there an easy and straightforward way to do this in R? Maybe a little example facilitates understanding our

Hi, I had a hard time in learning nlm in R and appreciate any help. I encounted the following error message from time to time when I tried different starting parameter values (three parameter values in this case) in nlm(f=SS.fun,p=c(0.1/40,0.1,2),hessian = FALSE,N.measure=object,h=20) Error in f(x, ...) : only 0's may mix with negative subscripts Basically I know the three parameter

Dear List, With regard to the question I previously raised, here is the result I obtained right now, brglm() does help, but there are two situations: 1) Classifiers with extremely high AIC (over 200), no perfect separation, coefficients converge. in this case, using brglm() does help! It stabilize the AIC, and the classification power is better. Code and output: (need to install package:

Dear R-users, I use glm() to do logistic regression and use stepAIC() to do stepwise model selection. The common AIC value comes out is about 100, a good fit is as low as around 70. But for some model, the AIC went to extreme values like 1000. When I check the P-values, All the independent variables (about 30 of them) included in the equation are very significant, which is impossible, because we

Hi, I run the following tuning function for svm. It's very strange that every time i run this function, the best.parameters give different values. [A] >svm.tune <- tune(svm, train.x, train.y, validation.x=train.x, validation.y=train.y, ranges = list(gamma = 2^(-1:2), cost = 2^(-3:2))) # where train.x and train.y are matrix

Hi, I am writing a program to plot the correlation coefficients of 45 elements using the commend "plot". Error message "Error in plot.new() : figure margins too large" appeared. I think it may because there are too many elements. But I really need to find their correlation coefficients. What can I do? Thank you. Maggie [[alternative HTML version deleted]]
