Haha, so I hope this isn't too late but I fixed the namespace issue. And I'm writing the is_id
(I think I'm going to use is_unique
though) right now :)
from assertr.
Perhaps assertr::assert_not_na(df, var)
is too long.
How about assertr::nona(df, var)
?
Also, Stata has a command isid
that verifies if a variable, or a combination of several variables, is uniquely identified. Maybe assertr
can have a similar function? Something like
assertr::isid(df, var)
assertr::isid(df, var1, var2)
I'm happy to submit a PR if you think these are useful functions to have.
Of course, nona
and isid
are not verbs, and they can be easily generated with assertr
and magrittr
's functional sequences. I understand if you think assertr
is not a right place for these special functions. I can also put them into a separate small package. Maybe as a place to include special functions:
comfirmr::nona(df, var)
comfirmr::isid(df, var)
comfirmr::isdummy(df, var)
comfirmr::positive(df, var)
comfirmr::negative(df, var)
comfirmr::nonzero(df, var)
from assertr.
(a) thanks for the kind words about the package!
(b) is_id
is on the radar! The project is about to be subsumed by ROpenSci so there's a lot of great stuff coming
(c) yeah, assertr
might not be the right place for these but they can totally exist in a different package! Before anyone works on that, we should wait to see how the collaboration with ROpenSci will change the way some of those functions are implemented; the API won't change, but there might be changes that will effect the most graceful way to write those convenience functions.
(d) I'm not sure about the namespace thing :( I'll look into it
