Hi!
First of all: IANAL, please get one :-).

I'm writing a small package that implements this web-bases effect size

The calculator is licensed under the Creative Commons

use this license for my package? And if so, is this a valid license for
R packages?
You can probably license your package CC-BY-NC, but you should be aware
that this is not an open source license. I would even say that 95% of R
users would not be able to use your package.
CC discourages usage of this license for software [1], and the
"noncommercial" aspect is incompatible with all existing definitions of
(F)OSS.
I'm happy to use any appropriate license, but I wanted to be sure to be
formally correct.
I don't really understand how you want to use the linked file. Are you
re-implementing the functionality? If so, you are not using the software
but the idea. I would recommend to get in touch with the original author
and ask if you can use a regular open source license [2, 3].
Hope this helps,
Daniel
