I think the logic Jeff had in mind is that R order() uses C do_order() for
method="shell" and since do_order() uses orderVector1() by induction it is the
shell-sort implementation.
order() itself uses whatever you specify in method=.

You asked how order works. From the R source you can follow which C functions
are executed, and since you seem familiar with C you can answer your own
question.

Hi Jeff,
Yes I did. My question is about R_orderVector1 which is part of public R C
api.
Should I notice something relevant in the source of R's order?

Dear pkg developers,
Are there any ways to check which sorting algorithm is being used when
calling `order` function? Documentation at
https://stat.ethz.ch/R-manual/R-devel/library/base/html/sort.html
says it is radix for length < 2^31
On the other hand, I am using R_orderVector1, passing in doub
