Dear list, I?m trying to register Fortran routines in randtoolbox (in srt/init.c file), see https://r-forge.r-project.org/scm/viewvc.php/pkg/randtoolbox/src/init.c?view=markup&root=rmetrics. Reading https://cran.r-project.org/doc/manuals/r-release/R-exts.html#Registering-native-routines and looking at what is done in stats package, I first thought that the following code will do the job:

Have you tried using tools:::package_native_routine_registration_skeleton()? If you don't like its output, you can easily edit its results and still avoid most pitfalls.

Dear Willem, Personally, I use the R-forge project for the distribution CTV : https://r-forge.r-project.org/projects/ctv/ It?s an alternative option to github.

Thanks for your email. I try to change the name in lowercase but it conflicts with a C implementation also named halton. So I rename the C function halton2() and sobol2() while the Fortran function are HALTON() and SOBOL() (I also try lower case in the Fortran code). Unfortunately, it does not help since I get init.c:97:25: error: use of undeclared identifier 'halton_'; did you mean

Dear list, I?m maintainsing a package containing only datasets (152): http://dutangc.free.fr/pub/RRepos/web/CASdatasets-index.html <http://dutangc.free.fr/pub/RRepos/web/CASdatasets-index.html> When R CMD checking the package, I get the following NOTE * checking data for non-ASCII characters ... NOTE Note: found 4 marked UTF-8 strings I wonder how to find which dataset(s) (all recorded

Dear list, The following example of constrOptim() where the initial point is the solution shows that the component counts is not a two-element vector as documented in the man page. constrOptim(c(1,1), fr, grr, ui = diag(2), ci = c(0,0)) Does anyone have the same behavior? A possible solution is to put line 69 in constrOptim.R before the first possible break line 67. Regards, Christophe

Hi all, Sorry if this doesn't end up in the thread. Tobias Verbeke forwarded that e-mail to me, because he thought I would be interested in maintaining the Programming Tools CTV. I wasn't subscribed to R-devel yet, but I would indeed like to volunteer to maintain the Programming Tools CTV. It will be my first time creating a CTV, so some guidance on getting it setup will be appreciated.

Hi all, I'm currently working on the fitdistrplus package (that basically fit distributions). There is something I do not understand about the generic function summary. In the current version on CRAN, there is no NAMESPACE saying S3method(summary, fitdist) . However if we use summary on an object send by fitdist function it works fine... According to R-lang, we have " The most

Hi all, I tried to a nice legend with small boxes filled with the colors used for the plots. But it does nor work, boxes are always filled with black. An example is here plot(1:4,1:4) lines(1:4,4:1, col="blue") legend("top",leg=c("a","b"),col=c("black","blue"), fill=TRUE) How could I specify the colors? the argument col.box is the

Hi, I have a problem when checking the package 'probdistr' (on probability distributions). I got this warning * checking index information ...

Dear list, Don't you think it could be useful to have in R base a function rowCumSums, that compute cumulative sums for each row of a matrix? My implementation of rowCumSums is rowCumSums <- function(x) t(mapply(function(row)cumsum(x[row,]), 1:NROW(x))) I'm sure it can be improved to have other arguments like na.rm or dims. Is there any hope to have this function in R?

Hi all, I use the symbol functions to draw circles. But the argument lty does not work on windows but works correctly on my macbook: x <- -4:4 y <- -4:4 plot(x,y,type="n") symbols(0, 0, add = TRUE, circles = 1, inches = 1, fg="black", lty="solid") symbols(0, 0, add = TRUE, circles = 1, inches = 2, fg="black", lty="dashed") The

Dear useRs, I have just discovered that the R optim function does not return the number of iterations. I still wonder why line 632-634 of optim C, the iter variable is not returned (for the BFGS method for example) ? Is there any trick to compute the iteration number with function call number?

Hi useRs, I'm trying to fit a basic AR(2) model with the 'ar' function. And when I try to check the value of the coefficients, I could not find the same value as the 'ar' function. Here is my example: myserie <- c(212, 205, 210, 213, 217, 222, 216, 218, 220, 212, 215, 236) #plot(myserie, type="l") myserieminus0 <- tail(myserie, -2) myserieminus1 <-

Dear all, I have just found a 'good' tutorial R for datamining. I think it should be on the contributed docs. http://cran.r-project.org/other-docs.html Here is the link http://www.liaad.up.pt/~ltorgo/DataMiningWithR/ What do you think?

Dear all, Using rmultinom() in a stochastic model, I found this function returns an error message 'NA in probability' for an infinite probability. Maybe, a more precise message will be helpful when debugging. > rmultinom(1, 3:5, c(1/2, 1/3, Inf)) Error in rmultinom(1, 3:5, c(1/2, 1/3, Inf)) : NA in probability vector > rmultinom(1, 3:5, c(1/2, 1/3, NA)) Error in rmultinom(1,
