How’s it going everyone?! Well, I decided to join Thomas Mock’s #TidyTuesday on twitter and this is my second submission. I’ll write a second post on my first submission because that took a little longer to figure out. Anyway let’s get going! First, let’s import the necessary packages

library(tidyverse)
library(rjson)
colors <- fromJSON(file = "~/Code/tidy_tuesday/Week_3/colors.json")

Rjson is only needed for my color palette, which I created as a JSON from here. I also imported my color palette as the vector named colors. Next, since I want to be able to produce as many as these plots as I want, I created a function that would let me avoid redundance. The function first checks whether we’re computing for the entire world or just a country, then does the necessary tidying up and plotting. Of course, in order to create the function I first explored the dataset. This is just the finalized product.

plotting_function <- 
  function(
    data,
    yearOfInterest,
    countryName,
    title = paste("Share of death by cause, ", countryName, ", ", yearOfInterest, sep = ""),
    subtitle = "",
    caption = "Source: IHME, Global Burden of Disease"
  ){
    if (countryName == "World") {
      data <- data %>% 
        filter(year == yearOfInterest) %>% 
        select(-c(country, country_code, year)) %>% 
        summarize_all(funs("sum"))
    } else {
      data <- data %>%
        filter(year == yearOfInterest, country == countryName) %>%
        select(-c(country, country_code, year))
    }
    data %>% 
      gather(key = "disease", value = "deaths") %>% 
      mutate(deaths = deaths / sum(deaths)) %>% 
      ggplot(aes(x = reorder(disease, deaths), y = deaths, fill = disease))+
      geom_bar(stat = "identity")+
      geom_text(aes(label = paste(round(100 * deaths, 2), "%")), hjust = -0.1)+
      scale_y_continuous(labels = scales::percent, limits = c(0, 0.35))+
      scale_fill_manual(values = colors)+
      guides(fill = FALSE)+
      coord_flip()+
      xlab("")+
      ylab("")+
      theme_classic()+
      labs(title = title, subtitle = subtitle, caption = caption)+
      theme(
        panel.grid.major.x = element_line(linetype = "dotted", color = "#5043484A")
      )
  }

So let’s try it out on the dataset! First we import the data with readxl and use stringr to remove the percentage signs from the variable names. I also decided to omit NA’s, which I think is why my numbers are slightly different from those in the article. Oh well shrug

data <- readxl::read_xlsx("~/Code/tidy_tuesday/Week_3/global_mortality.xlsx") %>% 
  rename_all(funs(stringr::str_remove_all(., "[(%)]"))) %>% 
  na.omit()

Finally, let’s use the function on the world, the US, and my beloved Chile for 2016.

plotting_function(data = data, yearOfInterest = 2016, countryName = "World")

plotting_function(data = data, yearOfInterest = 2016, countryName = "United States")

plotting_function(data = data, yearOfInterest = 2016, countryName = "Chile")

Nice! Of course, we could input any country and year and get the same kind of plot. That’s all friends!
