Function/file names are hypothetical. Say I have written myfunction.R, which calls myfunction.c via .C("myfunction", ...). I've compiled successfully myfunction.c via R CMD SHLIB myfunction.c in the terminal. Then, in the R console: dyn.load("myfunction.so") source("myfunction.R") test <- myfunction() # works fine So everything is in order, myfunction works

Hello everybody, I am looking for a function (or package) which can solve a integer optimization problem. I have found the glpk package but I don't known very well how to use it. Someone has another solution ? thx

... sorry for reposting this in a more appropriate forum than r.general ... Hello, I just don't get this and would appreciate if someone could write a line or two: I'm trying to build this package and it stops installing after I add the following to the NAMESPACES file: >importFrom(gsubfn,strapply) The error during the package test is: Error in MyPackage::MyFunction : package

Hello, I just don't get this and would appreciate if someone could write a line or two: I'm trying to build this package and it stops installing after I add the following to the NAMESPACES file: >importFrom(gsubfn,strapply) The error during the package test is: Error in MyPackage::MyFunction : package 'MyPackage' has no name space and is not on the search path Calls:

Dear all, My package has Depends: lme4.0 in the DESCRIPTION. I need to extract the fixed effect of a model and their standard errors. I use coef(summary(model)) inside a function to do that. Model is the output of a call to glmer() from the lme4.0 package. coef(summary(model)) throws an error: $ operator is invalid for atomic vectors I have tracked it down to a problem with summary(model)

I need to access some internal function of a package temporarily. These functions normally that are not visible outside of the package. I know the MyPackage:::myfunction mechanism, but that does not solve my problem. Instead, I need to add the "internal namespace" of the package to the search path, then I can run a few commands with these functions available, and then the internal

Hello, I would know if it is possible with grep to match a exact string. For example, I want to match the string "DP2" (and only this) and grep match "DP2BS" too. I have sought in the grep help but I didn't find what I want.

Let's say I have a package that consists of a set of functions, fig1(), fig2(), fig3() ..., each of which produces a plot, and perhaps some printed output, e.g., fig1 <- function() plot(1:10) fig2 <- function() plot(10:1) fig3 <- function() {y<-sample(1:10,10); plot(y); y} I'd like to produce a document (PDF or HTML) containing the listing of each function and its output,

I'm getting the following form R CMD CHECK mypackage ----------- * checking Rd files ... WARNING Error in Rd[[which]] : subscript out of bounds problem found in ?myfunction.Rd? --------- This is... not the most helpful error. I'd be happy to make a minimal .Rd example file if someone can point me to what a minimal .Rd file has in it. The file is already pretty minimal, so it's

How does one go about invoking a method within a namespaced package if that package has not been loaded via library method? Given "mypackage" and method "foo" within: mypackage::foo(1, 2, 3) Executing the same method's function call: do.call("foo", list(1, 2, 3)) didn't work. Nor did the following: do.call("mypackage::foo", list(1, 2,

I am being asked to modernize the Depends line in the DESCRIPTION file of some packages. Writing R Extensions says: The general rules are Packages whose namespace only is needed to load the package using library(pkgname) must be listed in the ?Imports? field and not in the ?Depends? field. Packages listed in imports or importFrom directives in the NAMESPACE file should

Dear R-ers, I hope there is a really simple solution to my problem. I've written a function that I saved in an .r file. I source this file in my code. For a while it worked fine. But then when I run the line: source("F mylineplot.r") I started getting a warning: In readLines(file) : incomplete final line found on 'F mylineplot.r' I have no idea why - I tried to check and

Dear all, I have the following problem: I have written a function genereating to plots, eg myfunction <- (data, some.parameters) { #some calculations etc . par (mfrow=c(1,2)) plot1(......) plot2(.....) } which works fine. But for analysing several variants, I tried a slope, eg: par (mfrow=c(5,5)) for ( i in 1:10) { myfunction(data, i) } Off

Hi, When I want to output a png file, I have the following error message : Error dans X11(paste("jpeg::", quality, ":", filename, sep = ""), width, : inpossible de d?marrer le p?riph?rique JPEG De plus : Warning message: impossible d'ouvrir le fichier JPEG 'Test.jpeg' or in english Error in X11(paste("jpeg::", quality, ":",

Hi, I have 15 or 20 functions I've written to convert the sort of data I'm working with. They are currently in their own R file which I load by hand in Rgui before loading and running my main programs. Is there any way to have this file included in my R program like #include might in C? If not is there a simple newbie-type example of how to create a package so I could just say

Hi, I am working at adding namespace to my packages, carefully following the doc "Writing R extensions" and some threads on the web. However I cannot find clear explanation about how to best deal with the import or importFrom functions in the name space. To make it short: To declare dependencies in the description file either after Depends: (packages including functions that are

Suppose that I have Windows application using Code: LoadLibrary followed by Code: GetProcAddress It should be possible to load a library implemented in terms of POSIX function but I do not understand how. Should I load the dll.so file generated by winegcc or do i need a plain .dll file?[/code]

Apologies, I cannot see how to make a rero for this issue. I have a function that uses levels(r) tor return the RAT of a raster "r" when the function is sourced from a script source(".\R\function.r") it works fine. when the function is built into a package and sourced from there library(mypackage) using the same script file to make the package levels(r)[[1]] the same line

I have successfully completed building a package to contain the functions I commonly use. However, I need to have other packages installed in order for some of my functions to work. I've been studying the instructions on installing packages for about a month now, but still haven't figured this one out. From what I do understand, to import additional packages I need some combination of

Hi I have a package which was built using R 1.9.1 and everything worked fine. I recently upgraded to R 2.0.1 and tried to re-install my package - and I got: Error in library(mypackage) : 'mypackage' is not a valid package -- installed < 2.0.0? So I tried rebuilding it using my new version of R: R CMD BUILD --binary mypackage hhc: not found cp: cannot stat `mypackage.chm': No
