I'm currently on ggplot2 version 3.3.2, and R version 3.6.1. I understand to use ggally, I need to be on ggplot2 3.3.4 or higher. But I'm having trouble upgrading ggplot2.
It prompted me to pick a CRAN mirror, but nothing happened after. ggplot2 is still on version 3.3.2 after.
Is it possible that I also need to upgrade R itself? Here's what my R sessionInfo() and repos look like

Is it possible my R is pinned to a version that doesn't allow for upgrading of ggplot2?
