I have 2 data frames which look like:
# A tibble: 52 × 2
provincia mean_price
<chr> <dbl>
1 A Coruña 137624.
2 Albacete 2115.
3 Alicante 31798.
col1 col2 col3 col4
1 04 Almería Almería <NA>
2 11 Cádiz Cádiz <NA>
3 14 Córdoba Córdoba <NA>
I am trying to join them together using full_join but not all of the names are being matched correctly due to differences in the spelling. I can run the following (with corresponding output):
df1 %>%
full_join(df2, by = c("provincia" = "col2"))
# A tibble: 60 × 5
provincia mean_price col1 col3 col4
<chr> <dbl> <chr> <chr> <chr>
1 A Coruña 137624. NA NA NA
2 Albacete 2115. 02 Albacete NA
3 Alicante 31798. NA NA NA
4 Almería -210404. 04 Almería NA
So it was able to match up many of the names but it failed on a few. In another column I have different variations of the spellings:
df1 %>%
full_join(df2, by = c("provincia" = "col3")) %>%
drop_na(col4)
provincia mean_price col1 col2 col4
<chr> <dbl> <chr> <chr> <chr>
1 Lugo -134055. 27 Lugo Lugo
2 Pontevedra -374778. 36 Pontevedra Pontevedra
3 La Coruña NA 15 Coruña, A A Coruña
4 Orense NA 32 Ourense Ourense
So I have 2 data frames I want to join, in df1 the column doesn't change, its always provincias - in df2 if the name did not match in col1, try col2, then try col3 and so on until all of the columns have been applied to try and full_join the data.
Some of the problem examples are:
In df1 we have
A Coruña
Alicante
Castellón
In df2 we have:
col2 = Coruña, A
col3 = La Coruña
col4 = A Coruña # joined up using this
and
col2 = Alicante/Alacant
col3 = Alicante # joined up using this
col4 = NA
and
col2 = Castellón/Castelló
col3 = Castellón # joined up using this
col4 = NA
Expected output: Trying to create a function to map over/ loop over and try to join the data together, moving along the columns if the previous column did not join successfully.

In case we want to do the join sequentially on each of the col2, col3, col4, here is one method with powerjoin
library(powerjoin)
library(purrr)
out <- map(names(df2)[-1],
~ regex_left_join(df1, df2, by = c("provincia" = .x))) %>%
reduce(power_left_join, by = c("provincia", "mean_price"),
conflict = coalesce_xy)
