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