Hi, as a beginner, I am working through the monograph "Introduction to R for Social Scientists by Ryan Kennedy and Philip D. Waggoner. Up to now I have set the working directory, set up an R project and loaded packages (e. g. tidyverse and here). But now I am stuck. Unfortunately, I am neither able to load the library, save data in my working directory (nor loading the data from it).
If you could help me, I would be very grateful. J
