The function sprintf() produces a string, which is then printed
using R formatting. You probably expected the following.
> cat(sprintf("%s is %f feet tall\n", "Sven", 7.1))
Sven is 7.100000 feet tall
Compare also
> s <- sprintf("%s is %f feet tall\n", "Sven", 7.1)
> cat(s)
Sven is 7.100000 feet tall
> print(s)
[1] "Sven is 7.100000 feet tall\n"
