R Markdown

This is an R Markdown document. Markdown is a simple formatting syntax for authoring HTML, PDF, and MS Word documents. For more details on using R Markdown see http://rmarkdown.rstudio.com.

When you click the Knit button a document will be generated that includes both content as well as the output of any embedded R code chunks within the document. You can embed an R code chunk like this:

summary(cars)
##      speed           dist       
##  Min.   : 4.0   Min.   :  2.00  
##  1st Qu.:12.0   1st Qu.: 26.00  
##  Median :15.0   Median : 36.00  
##  Mean   :15.4   Mean   : 42.98  
##  3rd Qu.:19.0   3rd Qu.: 56.00  
##  Max.   :25.0   Max.   :120.00

Including Plots

You can also embed plots, for example:

Note that the echo = FALSE parameter was added to the code chunk to prevent printing of the R code that generated the plot.

Task 1

Provide code and answer.

Prompt: in the tutorial, we calculated the average trust in others for France and visualized it. Using instead the variable ‘Trust in Parliament’ (trstplt) and the country of Spain (country file provided on course website), visualize the average trust by survey year. You can truncate the y-axis if you wish. Provide appropriate titles and labels given the changes. What are your main takeaways based on the visual (e.g., signs of increase, decrease, or stall)?

Task 2

Provide answer only.

Prompt and question: Based on the figure we produced above called task2_plot, tell us: what are your main takeaways regarding France relative to Italy and Norway? Make sure to be concrete and highlight at least two important comparative trends visualized in the graph.

ANSWER: In task2_plot there are clear trends being indicated. One trend found was that there is a continuous decline with proportion in each country (France, Italy, Norway). Even though eaach country is declining France has a steeper downwords slope starting in 1960, whereas Italy’s decline starts in the 1980’s.

## Task 3

Provide code and answer.

Question: What is the marginal percentage of Italian men who feel close to a particular political party?

italy_data <- read.fst("italy_data.fst")

italy_data <- italy_data %>%
  mutate(
    gndr = case_when(
      gndr == 1 ~ "Male",
      gndr == 2 ~ "Female",
      TRUE ~ NA_character_  # Set anything that is not 1 or 2 to NA
    ),
    clsprty = case_when(
     clsprty == 1 ~ "Left",       # Left-wing (0 to 3)
      clsprty == 2 ~ "Right",     # Right-wing (7 to 10)
      TRUE ~ NA_character_  # Moderate (4, 5, 6) and special codes (77, 88, 99) set to NA 
    )
  )

clsprty <- italy_data %>%  
  filter(!is.na(clsprty), !is.na(gndr)) %>%  # Filter out rows where 'lrscale' or 'gender' is NA (missing data)
  group_by(gndr, clsprty) %>% 
  summarise(count = n(), .groups = 'drop') %>%  
  mutate(percentage = count / sum(count) * 100)  
clsprty

## 2 Female Right    3228       34.2
## 3 Male   Left     1936       20.5
## 4 Male   Right    2593       27.5

Task 4

Provide code and output only.

Prompt: In the tutorial, we calculated then visualized the percentage distribution for left vs. right by gender for France. Your task is to replicate the second version of the visualization but for the country of Sweden instead.

sweden_data.fst <- read.fst("sweden_data.fst")
sweden_data <- read.fst("sweden_data.fst")

    ),

      lrscale %in% 0:3 ~ "Left",       # Left-wing (0 to 3)
      lrscale %in% 7:10 ~ "Right",     # Right-wing (7 to 10)
      TRUE ~ NA_character_  # Moderate (4, 5, 6) and special codes (77, 88, 99) set to NA 
    )    
  ) 

lrscale_percentages <- sweden_data %>%  # Begin with the dataset 'sweden_data'

  summarise(count = n(), .groups = 'drop') %>%  # Summarise each group to get counts, and then drop groupings
  mutate(percentage = count / sum(count) * 100)  # Calculate percentage for each group by dividing count by total count and multiplying by 100

  # Create horizontal bar chart
  geom_col() +  # Draws the bars using the provided data
  coord_flip() +  # Flip coordinates to make bars horizontal

  # Remove fill color legend
  guides(fill = "none") +  # Removes legend for the fill aesthetic

  # Split the plot based on Political Orientation
  facet_wrap(~ lrscale, nrow = 1) +  # Separate plots for Left/Right

  # Labels and titles for the plot
  labs(x = "Percentage of Respondents",  # X-axis label
       y = NULL,  # Remove Y-axis label
       title = "Political Orientation by Gender",  # Main title
       subtitle = "Comparing the percentage distribution of left vs. right for sweden (2002-2020)") +  # Subtitle

  # Adjust visual properties of the plot

        plot.subtitle = element_text(size = 12),  # Format subtitle
