Left Join Error - Trying to Join England Region Map data with another dataframe

[31121993]

Hi my left join for two data frames is returning null values in the sense that. I am trying to join a dataframe with all the regions in the UK to an england multipolygon sf dataframe. The issue is after the left join the geometry points come back empty. Please help.

england_maps <- england_map %>%
mutate(NUTS_NAME= str_remove(NUTS_NAME,".*/"),
NUTS_NAME= str_trim(NUTS_NAME),
NUTS_NAME=record(NUTS_NAME, "SOUTH EAST (ENGLAND)", "SOUTH WEST (ENGLAND)", "NORTH EAST (ENGLAND)","NORTH WEST (ENGLAND)","YORKSHIRE AND THE HUMBER", "EAST MIDLANDS (ENGLAND)", "WEST MIDLANDS (ENGLAND)","EAST OF ENGLAND","LONDON")) %>%
right_join(diagnosis_1822, by = c("NUTS_NAME"))

Hi @31121993, for get a better help try to put a reproducible example of data.

FAQ: How to do a minimal reproducible example ( reprex ) for beginners

A minimal reproducible example consists of the following items: A minimal dataset, necessary to reproduce the issue The minimal runnable code necessary to reproduce the issue, which can be run on the given dataset, and including the necessary information on the used packages. Let's quickly go over each one of these with examples: Minimal Dataset (Sample Data) You need to provide a data frame that is small enough to be (reasonably) pasted on a post, but big enough to reproduce your issue. Let's say, as an example, that you are working with the iris data frame head(iris) #> Sepal.Length Sepal.Width Petal.Length Petal.Width Species #> 1 5.1 3.5 1.4 0.…

Why you use c in right_join? In R we use c for concatenate values of a vector not for one.

I agree with @M_AcostaCH that we need a reproducible example. Also, your question says "after the left join" but the code contains a right join. Regarding the empty fields, do they come from the mutated england_map data frame or the diagnosis_1822 data frame?
