right - that's why my comment on SPARK-15237 is that we should have a
different rd for each of "statsfunctions" instead of having all of them on one
rd. To clarify, currently, we have
1. column function `corr` in its rd file
2. DataFrame function `corr`, `crosstab`, `cov`, `freqItems` in one rd file
What I think we should have instead is
1. DataFrame function `corr` in one rd file
2. DataFrame function `crosstab` in one rd file etc..
3. column function `corr` should group with other column functions (or
least column stats functions) in one rd file with appropriate "multiple
functions in one rd" formatting as you have suggested
I think it is rather confusing to put both DataFrame `corr` on the same
pages as column function `corr`?
Thoughts?
