使用自写程序包部署Shiny应用程序 [英] Deploying a Shiny app using a self-written package

问题描述

我有一个正常工作的闪亮应用程序，它使用library(coral)，其中珊瑚是我自己写的一个包，安装在该闪亮应用程序的目录中.

I have a working shiny app which uses library(coral), where coral is a package I wrote myself, installed in the directory of the shiny app.

当我尝试将应用程序部署到Shinyapps.io上时，收到以下消息:

When I attempt to deploy my app onto shinyapps.io, I receive the following message:

Error: Unable to retrieve package records for the following packages:
- "coral"
Execution halted

根据我在网上可以收集到的信息，问题可能出在CRAN上没有珊瑚，因此Shinyapps.io无法从那里获取该软件包的记录.

From what I can gather online, the issue is probably that coral is not on CRAN, so shinyapps.io cannot get the records for that package from there.

这是对问题的正确描述吗?有没有简单的解决方案?

Is that a correct description of the problem? And is there a simple solution?

谢谢.

推荐答案

shinyapps.io具有devtools软件包， 它可以从GitHub安装软件包， 如果您不介意将包裹放在这里:

shinyapps.io has the devtools package, and it can install packages from GitHub, if you don't mind putting your package there:

library(devtools)
devtools::install_github("youruser/yourpackage")

devtools也具有其他功能，可以从其他来源安装， 例如，来自bitbucket的install_bitbucket()，来自任意URL的install_url()和来自磁盘上本地文件的install_file().

devtools has other functions too to install from other sources, for example install_bitbucket() from bitbucket, install_url() from an arbitrary url and install_file() from a local file on disk.

要从本地目录安装，可以使用install:

To install from a local directory, you can use install:

devtools::install('path/to/r/package/dir')
