问题 This question already has answers here : How do I install an R package from source? (7 answers) Closed last year .

问题 If you are a package author, you are hopefully well aware of upcoming changes in package structure when we move to 2.14 in about a week. One of the changes is that all packages will require a NAMESPACE, and one will be generated for you in the event you do not make one (the R equivalent of your Miranda rights in the US). So being good citizen I was trying to figure this out. Here is the section from R-exts: 1.6.5 Summary – converting an existing package To summarize, converting an existing

问题 OK, we're all familiar with double colon operator in R. Whenever I'm about to write some function, I use require(<pkgname>) , but I was always thinking about using :: instead. Using require in custom functions is better practice than library , since require returns warning and FALSE , unlike library , which returns error if you provide a name of non-existent package. On the other hand, :: operator gets the variable from the package, while require loads whole package (at least I hope so), so

问题 I am trying to reinstall a package that I was previously able to install and use. I was building a package of my own after my computer unexpectedly restarted and then I started to have problems loading the rpgraph package. So I decided to uninstall it and to reinstall it. When I did so I got the following error: library(devtools) library(rJava) install_github("Albluca/rpgraph") Downloading GitHub repo Albluca/rpgraph@master from URL https://api.github.com/repos/Albluca/rpgraph/zipball/master

问题 I am just playing with package structure. And to my surprise I can bypass the default classes by creating my package and class name with that name. For ex: I created a package called java.lang and Class is Boolean . When I import java.lang.Boolean it's not the JDK's version of Boolean . It's mine. It's just showing the methods of Objects which every object java have. Why so ? Why I am allowed to create the package java.lang ? And the program runs fine. Another baffle is if I create a Class

问题 I want to declare all packages that I want to use in emacs in a init.el file. I wonder if its possible to load the missing packages with e.g. MELPA when I startup emacs without going through the list and mark the ones I want to install? 回答1: New answer: While my original answer is still valid, I now use the method suggested by Jordon. use-package is a fantastic tool for tidy Emacs configurations. In fact, I was already using it for clean package loading when I wrote my original answer. At

问题 I am using NuGet in attempt to find a better way to share and update packages to share across multiple developers. I installed Nuget and after choosing the option "Manage | NuGet pakages", I installed the package "HtmlAgilityPack" and noticed it put a packages directory in my Solutions folder. So I assume if wanted to share this application with for other developers to work on, I had to add this package to my repository as well.... This is not exactly what I want as I prefer my packages

问题 I got this question as an assignment: Packages/Naming We have created lot of packages and defined classes and interfaces in them. We have also discussed the point we have to remember while naming them. In this assignment we will see how important naming is. Please change the package names in your previous assignment such that two packages have same name and analyze the result/errors that will be thrown. My Doubt: I am unable to think of a way(scenario) to demonstrate what has been asked.
