Once one package is downloaded as a zip file, this is kept into a Temp folder. BioGenerics is another R package, and the system is alerting you it is needed. You only need to install that package and maybe some other that are required as well

PS: I recommend you to install (and update) packages using RStudio for convenience

1. Install RStudio
2. In the console, write setRepositories() #upper and lower cases as shown
3. Use the keyboard to write 1 2 3 4 5 6 (leaving a space between numbers). This will select cran and bioconductor repositories
4. Then go to Tools/Install Packages
5. Write the desired packages in the windows, and hit Install

This way you can make easier the installation of packages an their dependencies

Hope this helps
