Exploratory Core packages, like dplyr or tidyr, cannot be upgraded from UI, but it can be done through a Script.

For example, we just noticed new version of tidyr 0.8.1 is released with some bug fixes.

You can install it with a script that looks like this.

devtools::install_version('tidyr', version = '0.8.1', repos = 'http://cran.us.r-project.org', type = "binary")

Create a Script and type in the above content of the script, and click right-hand-side top Save button.

If it’s successful, you will see a message like this.

At this point, you won’t need this script anymore, and if you did this from a project you will keep using, you probably don’t want it to run everytime you open the project. So, you can remove the Script now.

Then, please restart Exploratory.

After restart, if you open R Packages dialog, you can verify that the version of tidyr is upgraded to 0.8.1.
