Ever since UNCMBB team’s season ended about a month ago, I’ve been meaning to update the data in uncmbb package, and I finally got to it. Obviously the new version includes 2017-2018 season match results for both UNC and Duke MBB teams, but it also includes new features in wrapper functions that are useful when working with uncmbb package.

I forgot to take notes of the steps taken when I was submitting uncmbb to CRAN for the first time last year, and this time I remembered to do so and take some screenshots too. Below are some notes related to package submission:

• Update R and RStudio versions
  • This is one of the prompts asked when calling devtools::release(), which is almost¹ the final step in submitting a package to CRAN.
  • I didn’t really start with updating R and RStudio this time and only ended up doing so when I ran into this prompt.
  • For R version update, there seem to be much better ways to do it, but I ended up manually downloading latest R from CRAN and installing packages as I needed them, starting, e.g., with tidyverse. I could’ve copied over from previous version’s directory as well as personal directory, but I figured some packages needed to be updated anyway, so I might as well start anew with the packages.²
• Make changes/load all/install and restart/document/check, and commit as needed.
  • This workflow (constant cycles of cmd-shift-L/B/D/E) makes sure my package is ok on current OS, which is Mac.
• Travis CI builds linux (Ubuntu) binary package and makes sure package is ok on linux (Ubuntu).
  • I already added Travis-CI to uncmbb project during the season³ and added build badge to the package github page along with other badges⁴.
• Once CI is passed, run devtools::build_win()
  • This function builds windows binary package and makes sure package is ok on windows (runs R CMD check on windows).
  • Built package and check log are sent to email.
• Once devtools::build_win() is passed, run devtools::release()
  • The function performs a series of tasks, and for the first several attempts, I kept getting this warning: “…* checking top-level files … WARNING Conversion of ‘README.md’ failed: pandoc: Could not fetch…TlsExceptionHostPort (HandshakeFailed Error_EOF)”img.shields.io" 443…“.
    • It seemed pandoc had something to do with this warning, so after several searches, I ended up updating my pandoc via homebrew.
    • But even after I updated my pandoc, rmarkdown was still using the old version, and I found out I had to run brew link pandoc to use the latest version.
• Once devtools::release() is passed, do the following last step task:
  • Go to confirmation page provided in the submission confirmation email⁵.
  • Once confirmed on the page, there will be another cran submission confirmation email.
  • Less than an hour later, I received yet another email from CRAN team that says the updated package “is on its way to CRAN now”. Yay!
