"int" means "internal", not "integer". Sometimes you should read the
documentation.

Below please see it does not unless user is super cautious about
inserting "L" with inputs. I think seq.int should do coercion for me
before returning the sequence.
xx <- seq.int(1,10)
class(xx)
[1] "integer"
is.integer(xx)
[1] TRUE
xx <- seq.int(1,10, 2)
class(xx)
[1] "numeric"
is.integer(xx)
[1] FALSE
xx <- seq.int(1,10, 2L)
class(xx)
[1] "numeric"
is.integer(xx)
[1] FALSE
xx <- seq.int(1L, 10L, 2L)
class(xx)
[1] "integer"
is.integer(xx)
[1] TRUE
I think all of those should have same return value, if the function is
correctly named seq.int.
