Hi i am new to the tidyverse in R and trying to work on a project
My dataframe(ab):
Year Zip Total_Population Median_Income City State
1 2014 00601 18088 10833 Adjuntas PR
2 2014 00602 40859 16353 Aguada PR
3 2015 00603 53162 16323 Aguadilla PR
4 2015 00606 6415 14138 Maricao PR
5 2016 00610 28805 17265 Anasco PR
6 2016 00612 66251 17752 Arecibo PR
I have used mutate to create population to income ratio based on zip:
dmg_ratio <- ab %>% filter(Year %in% c(2014,2015,2016,2017)) %>%
group_by(Zip) %>%
mutate(Poptoincomeratio = Total_Population/Median_Income)
dmg_ratio
Output repex:
Year Zip Total_Population Median_Income City State Poptoincomeratio
2014 ZCTA5 00601 18088 10833 Adjuntas PR 1.67
2014 ZCTA5 00602 40859 16353 Aguada PR 2.50
2015 ZCTA5 00601 53162 16323 Adjuntas PR 3.26
I want to find the difference in this newly created mutation(Poptoincomeratio) from 2014 to 2016 per zip code to understand if there has been any change in the population to income ratio over the years. How would I be able to do this?
Actually, there is a workaround for this, I assumed you have 'Poptoincomeratio' columns filled for every single year Then, try this
library(tidyr)
new_ab <- ab %>% select(-Total_Population ,-Median_Income ) %>% spread(Year,Poptoincomeratio)
After this, you can apply mutate again to get the difference between two years.
