QUESTION
I want to pass all values in a dataframe as condition to dplyr::case_when() with stringr::str_detect() while using the respective column title als replacement value.
I have these two data frames:
...ANSWER
Answered 2021-Nov-25 at 20:38I'm not 100% sure the output you're looking for. However, I believe this is a step in the right direction. Rather than looping over the district values and checking for matches, I propose melting the district_stack
data and joining that new df
to the city names using a fuzzy string match.
That is what I understand is happening in the loop. You then have a dataframe in which you can replace the city
value using if_else
more easily.
I drew inspiration from this thread: dplyr: inner_join with a partial string match

I have tried to group the columns and transpose it, but haven't found a way to get where I wanted. This is my dataset:

QUESTION
Now I have named every name object in the var but the map still not working.
I want to map custom icons, which are defined in a json data object by the property name. I have multiple Icons. I wrote this code, but it's not working and my console says the error is in line 266,
..."Uncaught TypeError: Cannot read property 'createIcon' of undefined" but I can't figure out the error.
ANSWER
Answered 2020-Apr-06 at 17:22You get this error because in your jsonDataObject
you only have as name Lidl
and not REWE
and Netto Filiale
. Moreover there is not an object for Lidl
in your markerIcons
dictionary. If you include in your markerIcons
an object for Lidl
you should be good and not get the error.
