问题 The R package devtools seems the method of choice for installing R packages directly from their github repository, using the install_github() function. While doing so, not only the addressed github-package is installed, but also its direct CRAN-dependencies, i.e., the Depends and Imports as defined in the Description/Namespace files of the package. However, I am wondering if indirectly required packages such as those in turn required by the Depends and Imports packages become automatically

问题 I downloaded the Doomclassic Source Code and wanted to have a look at it. First I wanted to compile it to see if it actually works. So I followed the instructions and copied the .wad files into the base folder, openend the project and hit compile. Aside from the over 300 warnings and the missing files (mostly Images, which I mostly fixed) I have a strange error during teh compile phase and google is no help at all. It says: /Users/tobias/Library/Developer/Xcode/DerivedData/Doom

问题 I have spent a lot of time searching for an answer to what is probably a very basic question, but I just can't find the solution to my issue. The closest that I found was this exchange from a few years ago. In that case, the issue was the location of the sysdata.rda file in the correct directory within the package. That is not my issue. I have some variables that store things like color palettes that I amusing inside a package. These variables are only used inside my functions so I storing

问题 I am creating a package and for S3 methods I export them using ##' @method predict myclass ##' @export predict.myclass <- function(object,...) { } Now when I load the package, then predict works on object of the class myclass , but function predict.myclass is not exported. In the NAMESPACE I only get the entry S3method(predict,myclass) .

问题 I am writing a vignette for my R package. I want to include a .jpg image on the .Rmd file that will generate the pdf vignette. The question is: where should I store this image?

Should I just include the file there? Or should I include the image on a new folder inside 'inst/images' , as suggested for external data used
