similar to: Using "Rscript" in combination with "eval()" results in error

Hi, The code below (found in src/gnuwin32/system.c) is almost guaranteed to do the wrong thing if 2 Rterm processes are started at the same time (or less than 1 second apart, the resolution of time() being 1 second): /* tmpfile() seems not to work on Vista: it tries to write in c:/ ifp = tmpfile(); */ { char *tm; tm = getenv("TMPDIR"); if (!isDir(tm)) {

Sorry guys, didn't see your responses before sending mine. Thanks jeroen!! I'll test your version today and get back to you.

Dear List, I’m doing my first baby steps towards developing own R Packages and ran into the following problem: R CMD check mypackage works fine (no errors, no warnings) R CMD build mypackage works fine (no errors, no warnings) R CMD INSTALL –library=”C:\R\R-2.11.1\library” “something\mypackage\mypackage_1.0.tar.gz” works fine (no errors, no warnings) However, when I try loading the

Dear list, I came up with a two functions that flatten arbitrary deeply nested lists (as long as they're named; not tested for unnamed) and environments (see attachment; 'flatten_examples.txt' contains some examples). The paradigm is somewhat similar to that implemented in 'unlist()', yet extends it. I would have very much liked to build upon the superfast functionality

Dear list, I hope this is the right place to post a feature request. If there's exists a more formal channel (e.g. as for bug reports), I'd appreciate a pointer. I work a lot with named nested lists with arbitrary degrees of "nestedness". In order to retrieve the names and/or values of "bottom layer/bottom tier", I love the functionality of 'unlist()', or

Dear list, I was wondering if you could help me out in clarifying something: Is it possible to use class "ANY" in slots/fields of formal classes if you a) do not want to restrict valid classes of that field and b) if you are making explicit use of class inheritance? It seems to work in simple scenarios but produces errors when class inheritance comes into play. So I was

We have seen problems with a number of packages which use R/Rscript to run R code in configure or makefiles. (a) You must give a full path: there need be no version of R in the path, and if there is it might not be the version/build of R under which package installation is being done. So the general form is to use ${R_HOME}/bin/R to select the right version. And since ${R_HOME} might

Thanks a lot for answering. Before I get into it, please note that everything below bears the big capture "Thanks for trying to help me at all". 1) Yeah, those examples - quite hard to satisfy everyone's needs ;-) While the one side complained that my past examples regarding this issue were not informative enough, others didn't like the more elaborated version (as seems to be

Dear list, I've got the following problem: In a package I'm trying to build, there exists a method for the function "as.ts()". When checking the package, R always throws the error that it cannot find a function called "as.ts". To me it seems that the package "stats" (home of "as.ts()") is not loaded during the checking process even though

Dear list, I'm tackling an empiric research problem that requires me to address a whole bunch of conceptual and/or technical details at the same time which cuts time short for all the nitty-gritty details of the "components" involved. Having said this, I'm lacking the time at the moment to deeply dive into parallel computing and HTTP requests via RCurl and I hope you can help me

Dear list, somehow I can't get the Roxygen tag "@example" to work for me. My "Roxygen-Header" of a script containing, say, a function looks like this: #' My header #' #' My description #' #' @param a Blabla. #' @param b Blabla. #' @return \code{TRUE}. #' @callGraphPrimitives #' @references #'

Dear List, I am not really familiar with any other language than R, but I?ve heard that in other languages there is something called ?self referencing?. Here?s what I?m trying to get an answer for: Suppose there is a function that takes as its input a value of a slot of an S4 object. The function itself is stored in another slot of the SAME S4 object. Is it then possible to have the function

Dear R-devel members, recently, I ran into the following error message (R-devel 2018-01-31): 'Rscript' should not be used without a path -- see par. 1.6 of the manual I would like to know more about it, why is it required to run Rscript with a path, and where is that par. 1.6 of the manual. I get this error message during Travis r-devel build of my package for generating makefiles. I

Dear list, I have a reference class which should act as a "generic" superclass for other classes. I've read the respective section at ?setRefClass and put the name of the superclass to the 'contains' argument of an example subclass (see class defs below). Classnames are set in a way that shouldn't result in collation issues (virtual def sourced before superclass def

Hi there, is there a way to create a NAMESPACE file based on Rd-files (or whatever is needed in order to apply the regular expression "^[[:alpha:]]+" without(!) resorting to package.skeleton() (as this kind of interferes with roxygenize() pretty often)? Thanks a lot, Janko [[alternative HTML version deleted]]

It seems, I don't understand something, or there is a bug in R. I have made some experiments after my yesterday post about using "=" with -e switch to the Rscript. Now, I've found: (1) C:\users\wl\trainings\r>rscript --verbose -e "mean(x=1:3)" running 'C:\Program Files\R\bin\Rterm.exe --slave --no-restore -e mean(x=1:3)' Error in -args : invalid

Hi there, I''d like to choose between an "static" and "dynamic" access of a reference class field, say ''a''. myObj <- getRefClass("Blabla")$new() Static: myObj$a Dynamic: myObj$a.get() where the function retrieves the data from a database (or some other location), stores it to a buffer and
