Hi @cderv ,
ah yes indeed. the renv.lock is in the main folder of the RStudio Project, whereas the quarto book is at least one folder down. (I tried copying the renv.lock into the quarto book folder, but that did not help)
Any tipps on how I could make the quarto render aware that it is part of a project whose root folder is somewhere else? Or alternatively do you have another suggestion of how to set something like this up - a main analysis project and a quarto book which needs both the renv, some functions and data from the main project?
