addin drop down list not updated before restart R session about addinslist

[daattali]

That has nothing to do with the addinlist - in fact, if you look at the source code (or the console when clicking on an addin), my package just calls install.packages() or devtools::install_github(). I think when a package is installed using install.packages() then rstudio picks it up right away but when you install an addin from github then you have to restart

I tried again, it's like what you said. Interesting, when I tested my addin in a packrat project, the addin list got updated right after the installation...
