Hi @MauiWarrior , Yes, you can install all required packages at once.
You are facing this issue because some packages have dependencies on other packages and they need to be installed in a specific order.
You can use the install.packages function with the dependencies=TRUE argument in R to install a package and all its dependencies.
However, if you are facing issues, you can try to install all the packages manually in the correct order.
Alternatively, you can use a package like pacman in R which can help manage package dependencies. The p_load function in pacman can be used to load and install packages, it also checks for missing packages and installs them.
