Answer 1

Two questions, does it has be duplicated and do you have to use dplyr and tidyr?

Maybe this could be a solution?

(
bar <- data.frame(id=c(1,1,2,2,3,3),
                 email=c('bob@email.com', NA, 'joe@email.com', NA, NA, NA))
)                 
#> id         email
#>  1 bob@email.com
#>  1          
#>  2 joe@email.com
#>  2          
#>  3          
#>  3          

(                 
foo <- bar[!duplicated(bar$id),]
)
#> id         email
#>  1 bob@email.com
#>  2 joe@email.com
#>  3
