Hi Andy:
I don’t have an answer but I do have what I hope is some friendly advice.
Generally the more information you can provide, the more likely you will get
help that is useful. In your case you say that you tried several packages and
they didn’t do what you wanted. Providing that code,
what if you try lubridate::as_datetime('2017-02-28T13:35:00+03:00’)

Two suggestions. In the map statement, set silent = FALSE, hopefully that
will give you more info, The second is to try what is suggested in the error

Hi Janet:
here is a start to give you the idea, now you need loop either use a "for" or
one of the apply functions.
1. Preallocate new data (i am lazy so it is array, for example of size three.
2. order the data and set values.
junk <- array(0, dim = c(2,3))
values <- c(10, 30, 50)

Can I ask if this is the specific problem you are after, or a test for more
general problem? If the former, the derivative is
-0.0263 + 0.002 * B
so the solution for B is:
B = (0263)/0.002
If you are after a more general way fo doing this:

If I were a betting man I would bet that one of the things in your "pipeline"
isn't returning what you think it is. You can either break it out step by step
to check or this page lists a variety of resources to debug pipes:

The main thing is the data types that map view supports, so you must have a
raster or an spatial object like an "sf" object. So points would have to also
be an sf object and the two combined (sf has commands to do this) or perhaps
you can

I haven't used it to any extent to give you specifics, but I strongly suggest
