R: Passing multiple dataframe columns to dplyr::case_when() as condition while using column title as replacement

Asked 2021-Nov-25 at 20:38

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:

I'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

QUESTION

Specific transpose of my pandas Dataframe

Asked 2021-Oct-25 at 08:49

I have a dataframe that I would like to transpose in a certain way, in which the "attr" column values become columns instead of values, while price stays as a column.

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:

Uncaught TypeError: Cannot read property 'createIcon' of undefined when creating markers

Asked 2020-Apr-06 at 20:27

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 17:22

You 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.
