Dear community,

I’m new to DigitalOcean and still lack experience. I set up a Droplet with RStudio on Ubuntu 18.04. To run my code, I need to install the “pcalg” package. However, I always get the following error messsage. Does anyone have an idea how to fix this? Your help would be much appreciated.

> install.packages("pcalg")
