Question

我目前正在尝试使用Windows计算机上的计划任务部署闪亮的应用程序。我们的想法是每天早上运行一个脚本并汇总来自多个位置的数据，然后将其放入一些R data.table个对象中，以便在shiny应用中使用。

我正在使用taskscheduleR来安排任务。它最初将工作目录设置为C:/Windows/system32，因此我将其修复为指向应用程序所在的目录（C:/rprojects/myappname）。脚本运行正常，直到我尝试部署文件。

library(rsconnect)
deployApp(appName = "myappname", upload = TRUE, appFileManifest = "manifest.txt",account = "myaccountname", server = "shinyapps.io")

当我从taskscheduleR检查日志时，我有以下几行

Preparing to deploy application...DONE
Uploading bundle for application: 999999...Error in contrib.url(getOption("repos"), type) : 
  trying to use CRAN without setting a mirror
Calls: deployApp ... withCallingHandlers -> <Anonymous> -> available.packages -> contrib.url
Execution halted

我已经搜索了错误消息，我找到的所有内容都与使用我在脚本中不使用的install.packages()时设置回购有关。我希望它与deployApp试图找到URL的方式有关，但我可以理解我可能需要（或能够）声明存储库的位置。

更新（2016-10-11）： 我已为rsconnect激活了一些选项，以获取有关部署的更多详细信息。不幸的是，它没有提供更大的清晰度。

options(rsconnect.http.trace = TRUE)
options(rsconnect.http.trace.json = TRUE)
options(rsconnect.http.verbose = TRUE)

以下是log

的输出

Answer 1

set

options(repos = c(CRAN = "https://cran.rstudio.com/"))

somewhere at the top of your script which you wanted to launch with taskscheduleR If you launch R with Rscript, the CRAN repository is not set, which is different then if you run your code in the RStudio editor.

使用命令行
