问题 I am roxygenizing a package I am making in R. The script is #' HandyTools #' #' Check if required packages are installed or not and installs them if not #' @param packageList - a list containing the required package names #' #' @examples #' checkPackagesLibrary(c("lme4","epitools","roxygen2")) #' #' @export library(devtools) checkPackagesLibrary <- function(packagesList){ new.packages <- packagesList[!(packagesList %in% installed.packages(lib.loc="/data/legacy/user/R_Packages")[,"Package"])]

问题 I would like to create an R package that relies on executables that I put into the /inst folder. However, whatever I put in /inst loses the execution bit after the package is installed, hence the binaries become non-executable due to the missing bit. Is there a way to preserve the file mode for files in /inst or these execution bits need to be added post installation? If so, anyone knows how?

问题 My directory structure is as follows: c:/Users/bob/MyPackageName c:/Users/bob/MyPackageName/R c:/Users/bob/MyPackageName/tests c:/Users/bob/MyPackageName/tests/testthat My development session normally consists of starting an R session in the package root ( c:/Users/bob/MyPackageName ), and running devtools::load_all() devtools::test() followed by alternating the addition of little bits in MyPackageName/tests/testthat/mytest.R and in MyPackageName/R/mycode.R . When starting a session returns

问题 R CMD check packagename_0.1.1.tar.gz --as-cran produces a WARNING if badges are present in README.md . This causes consequences like travis CI to fail (since it treats warnings as errors) Is there a workaround to get the check to pass without removing the badges? 来源： https://stackoverflow.com/questions/56346524/workaround-to-allow-badges-in-package-readme-md-on-github-but-not-in-cran-versio

问题 I wrote an internal package and when I add a vignette, it does not pass devtools:check() anymore. I added the vignette with devtools::use_vignette("my-vignette") . Even if I do not change anything about the vignette template, running devtools::check() yields: ==> devtools::check() Updating DataReportR documentation Loading DataReportR Setting env vars -------------------------------------------------------------- CFLAGS : -Wall -pedantic CXXFLAGS: -Wall -pedantic Building DataReportR --------

问题 I am developing a package that suggests R's parallel package (So my DESCRIPTION has a Suggests: parallel (>= 1.13.1) statement. It compiles fine under OSX and Linux but fails when building on windows (using win-builder). Here is the end of the install.log that win-builder spits out: *** installing help indices ** building package indices ** installing vignettes ** testing if installed package can be loaded *** arch - i386 Error: package or namespace load failed for 'spectrolab' in library

问题 I'm currently writing my first R package, following Hadley Wickham's excellent book on the topic. The section of the book linked above includes examples for adding authors through the package's DESCRIPTION file. Dr. Wickham notes that "The full list of roles is extremely comprehensive. Should your package have a woodcutter ('wdc'), lyricist ('lyr') or costume designer ('cst'), rest comfortably that you can correctly describe their role in creating your package." The problem that I'm

问题 I created an R package and loaded it to github (microdadosBrasil). When I try to install the package (as a user would) I get the following error: devtools::install_github("lucasmation/microdadosBrasil") Error in loadNamespace(i, c(lib.loc, .libPaths()), versionCheck = vI[[i]]) : there is no package called ‘stringi’ I tried solving this by adding stringi to the package dependencies In DESCRIPTION in included: Imports: stringi I also included the package import at NAMESPACE import(stringi) But,

问题 Problem — I want to export a list of functions as part of an R package, ideally using roxygen2. To be more precise, I want to export the functions in the list, rather than the list itself. For example, consider a list of functions that are generated as closures, like so: addval <- 1:100 fns <- lapply(addval, function(y) {force(y); function(x) x + y}) names(fns) <- paste0("add_", addval) Then the problem is to bind the functions (using the same names in fns , for instance) to the package
