Dear R-helpers, The function optim implements algorithms that I would like to use. I have function implemented in R, which given the parameters of which minimization is to take place returns a scalar as well as the gradient. Unfortunately optim requires two function _fn_ and _gr_ where fn returns the function value and gr the gradient. Splitting my function in two functions would be easy,

Dear R-developers, Using .Call I pass a S4 class with e.g. the following class definition: setClass("mmatrix",representation( data="matrix") ) On the "C side" i do mat = GET_SLOT(vs,install("data")); and then: printf("%f\n",NUMERIC_POINTER(mat)[1]); The above print statement produces the correct output if xx<- new("mmatrix")

Dear R-developers, I am getting the following error message (see bottom of e-mail) and can't make a clue out of it. The zzz.R file contains .First.lib <- function(lib, pkg) library.dynam("SBMLodeSolveR",pkg,lib) .Last.lib <- function(libpath) library.dynam.unload("SBMLodeSolveR", libpath) There is a SBMLodeSolveR.so file in the src directory which works if loaded

Dear R-users, I have the following data x <- runif(300,min=1,max=230) y <- x*0.005 + 0.2 y <- y+rnorm(100,mean=0,sd=0.1) y <- y%%1 # <------- modulo operation plot(x,y) and would like to recapture the slope (0.005) and intercept(0.2). I wonder if there are any clever algorithms to do this. I was looking at the function lm.cirucalar. Is this the method to use? If, which of the

Dear R-devlopers, I removed yesterday the R.2.1. installation from windows NT laptop and I am getting the following error when building a pacage with R.2.2 ---------- Making package msbase ------------ adding build stamp to DESCRIPTION making DLL ... make[3]: *** No rule to make target `d:/prog/r/rw2011/include/R.h', needed by `llogic.o'.

Dear R helpers, I generate a qq plot using the following function call. qqmath(~val|ind,data=xx ,distribution=function(p) qt(p,df=19) ,ylab="Sample Quatinles" ,xlab="Theoretical Quantiles" ,aspect=1 ,prepanel = prepanel.qqmathline ,panel=function(x,y) { panel.qqmathline(y, distribution=function(p) qt(p,df=19),col=2)

Dear R-developers, I am trying to reproduce the autoconf.ac example from R-ext and fail. My autoconf file looks like this [autoconf.ac] # original by Friedrich Leisch, much changed by BDR AC_INIT([SBMLodeSolveR]) dnl Select an optional include path, from a configure option dnl or from an environment variable. AC_ARG_WITH([sbmlode-include],

Thanks for asking. The path where R tries to load the dll from does not exist I think (or the install process deletes it after the error - might this be the case?): C:/Users/wewol/OneDrive/Documents/R/win-library/3.5/grpc/libs/x64/grpc.dll' When I am checking after the error that path is only valid up to: C:/Users/wewol/OneDrive/Documents/R/win-library/3.5/ So maybe (?) the install process

Hi! I am trying to calculate a dissimilarity matrix using daisy. The matrix vectver is binary as i test with: > levels(as.factor(vectver)) [1] "0" "1" But the call to daisy gives me the following error message.: > dfl1 <- daisy(vectver, type = list(asymm = c(1:length(vectver[,1])))) Error in daisy(vectver, type = list(asymm = c(1:length(vectver[, 1])))) : at least

Hi! On the cran "package source" page, to each package there are the "reference manual" in pdf format with a nice title page. I observed that during the R CMD check pkg a pkg-manual.div are generated in the pgk.Rcheck directory. But the nice title page are missing. During the package build and install no div files are produced. Which opitions I have to pass during the build

I hope that someone reading this list can offer some suggestions on how I can incorporate external C libraries in C functions that I want to call from R. I have gone through all of the documentation, help files and mailing list archives and have not been able to find a satisfactory solution. I have constructed a simple example of the problem, since my "real" program is much more

Hi, Would like to use to the hexbin package to plot a 2D hist - because it looks really _cool_. My problem is related to drawing a pdf hexbin graphic in series of other graphics. All other figures have a par(mar=c(3.2,3.2,1,1)). So the gplot.hexbin figure in this series looks a little alienated? Was trying a to specify the _mar_ using par, viewport, hexViewport etc. a little. My question. How

Is there a library that is able for example to 1. merge 2 dataframes by row eg.: rbind(dataframe1, dataframe2):data.frame 2. delete a column from a dataframe del(dataframe, colname) or del(dataframe, colindex= 1):data.frame? 3. Select lines from a dataframe by a specific function ? select(dataframe, func=small(x){x<1}, colindex=3): data.frame? 4. converting all double columns of a data.frame

Hi! I would like to give my objects functions like "subset", "union", et cetera and name it also in this way. But this functions names are already used in the base package and they are not generic. I am right in that if they would be generic then i still can use the neat names with my objects? I have the impression that there are more and more packages are going to be

Hi! How can i send http Post and Get messages to a Web server from within R? Has anybody implemented a function like? form(action="http://big.thing.inf/cgi-bin/answer.pl",list(test="my",something="there"),method="POST"). Has anyone a package with a similar functionality like the LWP and HTTP::Request::Common packages in Perl? Or has anybody a function that

Dear Rgurus, To my knowledge the best way to visualize the distribution of a discrete variable X is plot(table(X)) The problem which I have is the following. I have to discrete variables X and Y which distribution I would like to compare. To overlay the distribution of Y with lines(table(Y)) gives not satisfying results. This is the same in case of using density or histogram. Hence, I am
