CS1B - R package install issue

Hi,

When I follow the instructions on installing packages that have been listed in the 'R_for_CS1_and_CS2_for_2023_Exams' document published by the IFOA I run into the following issue:

> install.packages("Rtools")
Warning in install.packages :

WARNING: Rtools is required to build R packages but is not currently installed. Please download and install the appropriate version of Rtools before proceeding:

This is using RStudio with R 4.2.1 on my work laptop. This is the laptop I am planning to sit the exam with.

Is anyone familiar with the issue here? Is it possibly due to security controls on my work laptop?

Thank you
