问题 Multiple R packages may be loaded using the function p_load function from pacman R package with the following command: pacman::p_load("ggplot2", "lme4") However, I want to use the command like this Packages <- c("ggplot2", "lme4") pacman::p_load(Packages) which does not work. Wonder how this can be achieved? 回答1: Set character.only on TRUE Packages <- c("ggplot2", "lme4") Packages %in% loadedNamespaces() # check if the packages are loaded # [1] FALSE FALSE pacman::p_load(Packages, character

问题 I'm trying to make the absolute smallest Docker image I can get away with, so I have switched from ubuntu as my base to alpine. For apt , I used to use --no-install-recommends to minimize "dependencies" installed with my desired packages. Is there an equivalent flag I need to pass along with apk or is this the default behavior for this slimmed down OS? 回答1: No it doesn't have the same flag I think because it does not even do the same behaviour of downloading recommended packages. However

问题 Okay so, I have this project structure: package A.B class SuperClass (this class is marked package private) package A.B.C class SubClass (inherits from super class) I'd rather not make SuperClass publicly visible... It is really just a utility class for this specific project (A.B). It seems to me that SubClass should be able to see SuperClass , because package A.B.C is a subpackage of A.B... but this is not the case. What would be the best way to resolve this issue? I don't think it makes

问题 I want to see all the java packages. Where are the packages stored in my machine? Can anyone help. I did search in jdk folder and found awt.dll and all. But its only a few. Can i see all of them? 回答1: If you want a list of packages in the standard installation, just go to the Javadocs and look in the upper left corner. If you want to see the .class files, they're in lib\rt.jar in the JRE directory ( .jar is the same as .zip , so you can open it with anything that can open zip files). If you

问题 Would it be a problem to delete *.tar.gz files in C:\Users\username\AppData\Local\conda\pkgs ? I also see subdirectories of Python of the same Python package, but in different versions (e.g., pandas-0.19.2-np111py27_1 , pandas-0.19.2-np111py35_1 , pandas-0.20.1-np112py27_0 , pandas-0.20.1-np112py35_0 , pandas-0.20.1-np112py36_0 , pandas-0.20.2-np112py27_0 , pandas-0.20.2-np112py36_0 , pandas-0.20.2-np113py36_0 ).
