One of the reasons that I specified the 'seq' command as it was was to
make sure it used numerics:
> x <- seq(123456789012.0, length = 10, by = 1.0)
> x
[1] 123456789012 123456789013 123456789014 123456789015 123456789016
123456789017 123456789018
[8] 123456789019 123456789020 123456789021
> str(x)
num [1:10] 123456789012 123456789013 123456789014 123456789015 123456789016 ...
