阅读更多关于 Trouble with packrat corrupting R functioning

问题 I installed the package packrat at some point, used it perhaps once and moved on with my life. However, despite not having loaded it in months, it remains a nuisance to my regular R usage. Seemingly at random, my R session within RStudio will fail with errors at certain operations, especially package installation. Here's the most recent error message (after running parallel::makeCluster(parallel::detectCores()) : Error in file(filename, "r", encoding = encoding) : cannot open the connection

I tried to find an option in Rstudio to disable it but could find anything. I therefore uninstalled R and RStudio by (on OSX 10.9.5) dragging the icons for R and RStudio from the applications folder to the trash. However, upon reinstallation of R (version 3.2.3), the R console displayed the following message and a pop-up prompted me to select a

问题 Can someone point me towards a working example where packrat is used with AppVeyor to build an R package? Searching through Google and GitHub, I can't find any packrat-enable package that uses AppVeyor. Does the appveyor.yml file need to change? Are there some settings I need to add through the AppVeyor website? I have a very minimal package ( testthat is the only dependency) that broke AppVeyor builds. Here is the code frozen for that commit. Here is the AppVeyor log. (If this SO question

My question is what is the
