Is it possible to group the R code for several pages of a website in one place to avoid repetition? I'm thinking of libraries and data reading?

Is it possible to group the R code for several pages of a website in one place to avoid repetition? I'm thinking of libraries and data reading?
I feel like I have to repeat the same code chunks calling libraries and data on every page (R).
