Cannot install tidycensus package without first installing rgdal package

[purdiea]

I attempted to install the tidycensus package but received the following error. To solve it, I ran install.packages('rgdal') first and then was able to install tidycensus. Can you add rgdal to the dependencies when downloading tidycensus to avoid this issue in the future?

>install.packages('tidycensus')


There is a binary version available but the source version is later:

rgdal should get picked up by tigris when tidycensus installs as it is a dependency of that package. What operating system are you on?

Reporting the same issue on Ubuntu 18.04 running R 3.6. Fixed by running

sudo apt install libgdal-dev
