It remains unclear what this apparent homework problem us supposed to be
teaching you to do. I see no constraints on alpha and beta, and you have shown
no effort to submit complete code.

I'm not a regular user of the rstudio IDE but maybe it incorporates a search
function? In a non-rstudio environment I would suggest:
install.packages("sos")
library(sos)
findFn("betabinomial")
# should also succeed in rstudio.
