I like doing stuff like the line below, especially when I'm using Sweave.
print(paste('Within the observation period,',nrow(desk),
'patrons approached the circulation desk.'))

But what if I want to put it at the beginning of a sentence?
print(sum(desk$deskchoice=='bookdrop'),'persons',
'used the book drop. Everyone else interacted with a staff member.')
Is there a pretty way to change the result of
sum(desk$deskchoice=='bookdrop')
from 2 to Two?

And what if the number is one?
print(sum(desk$deskchoice=='bookdrop'),
c('person','persons')[as.numeric(sum(desk$deskchoice=='bookdrop')!=1)+1],
'used the book drop. Everyone else interacted with a staff member.')
Is there a prettier way of choosing between person and persons?
Using John Fox's numbers2words found here:
http://tolstoy.newcastle.edu.au/R/help/05/04/2715.html
and capwords found in the examples section of ?toupper try this:
n - sum(desk$deskchoice == bookdrop)
paste(capwords(numbers2words(n)), if (n == 1) person else
people, used the book drop...)
