# LAPOP Visualization Guide

## Introduction

This vignette demonstrates how to use the `lapop` package to reproduce figures style from the 2023 Pulse of Democracy report.

Attention: we are only using a subset from the data used in the actual report.

## Load Packages

    library(lapop)

The lapop package brings two datasets already with design effects (weighted).

    # Single-country Single-year AmericasBarometer 2023 Brazil
    data(bra23)

    # AmericasBarometer 2006-2023 Brazil Merge
    data(cm23)

    # AmericasBarometer 2023 Year Merge
    data(ym23)

### Survey Design for the Data

The AmericasBarometer use `weight1500` for comparative datasets by time or country, `wt` weights are only for country specific datasets (single-country single-year). In the AmericasBarometer the primary sampling units (ids = upm) and stratification variable (strata = strata) to account for the survey’s complex design. Finally, PSUs are nested within strata, properly reflecting the survey’s hierarchical sampling structure. The `lpr_data()` function apply survey design effects.

    # Single-Country Single-Year
    bra23w <- lpr_data(bra23, wt = TRUE)

    print(bra23w)

    ## Stratified 1 - level Cluster Sampling design (with replacement)

## Fonts for 2023 Pulse of Democracy report.

When you load `lapop` with `library(lapop)`, the package now auto-registers the bundled LAPOP fonts and enables the standard plotting setup. You can still call `lapop::lapop_fonts()` manually if you want to re-run font registration in the current session.

    lapop::lapop_fonts() # Re-run font registration explicitly if needed

              subtitle = "% who trust...")

## Figure Mover Example: Satisfaction with Democracy

    library(dplyr)

    ym23w$variables <- ym23w$variables %>%
        mutate(
        edrer = as.numeric(edre),
        gender = as.numeric(q1tc_r)
      ) %>%
      mutate(edrer = case_when(
        edrer <= 2 ~ "None/Primary",
        edrer %in% c(3, 4) ~ "Secondary",
        edrer > 4 ~ "Superior",
        TRUE ~ NA_character_
      ),
      edrer = factor(edrer, levels = c("None/Primary", "Secondary", "Superior")),
      gender = ifelse(q1tc_r == 3, NA, q1tc_r)) %>%
      mutate(gender = case_when(
        gender == 1 ~ "Men",
        gender == 2 ~ "Women",
         TRUE ~ NA_character_
      ))

    # Changing legend for readibility
    attributes(ym23w$variables$gender)$label <- "Gender"
    attributes(ym23w$variables$edrer)$label <- "Education"
    attributes(ym23w$variables$wealth)$label <- "Wealth"

    fig_mover <- lpr_mover(ym23w,
                           outcome = "pn4",
                           grouping_vars = c("gender", "edrer", "wealth"),

                subtitle = "% who are satisfied with democracy")

## Figure Histogram: Citizens’ Views

    spot32_data <- lpr_hist(ym23w, outcome = "vb21n")

    # Translating to English
    spot32_data$cat <- c("Vote", "Run for\noffice",
                         "Protest",
                         "Participate\nin local orgs.",
                         "Other",
                         "Change is\nimpossible")

    lapop_hist(spot32_data,
               main_title = "On average in the LAC region, one in three say voting is the best way \nto influence change",
               subtitle = "How do you believe you can best influence change?")

## Figure 3.5: Dumbell Plot

    fig3.5_data <- lpr_dumb(ym23w,
                            outcome = "q14f",
                            rec = c(1, 1),
                            over = c(2018, 2023),
                            xvar = "pais",
                            ttest = TRUE)

    # Select Countries
    fig3.5_data <- fig3.5_data[c(1:3,5:6), ]

    lapop_dumb(fig3.5_data,
               main_title = "Among those with emigration intentions, the percentage who say they are \nvery likely to emigrate increased in Nicaragua and Guatemala",
               subtitle = "% who say it is very likely they will emigrate",
               source = "LAPOP Lab, AmericasBarometer 2018/19 and 2023")

## Figure 3.8: Stack Plot by Country

    attributes(ym23w$variables$q14f)$label <- "Migration intentions"

    fig3.8_data <- lpr_stack(ym23w,
                             outcome = "q14f",
                             xvar = "pais",
                             order = "hi-lo")

    lapop_stack(fig3.8_data,
                xvar = "xvar_label",
                source = "LAPOP Lab, AmericasBarometer 2023",
                main_title = "Nicaragua has the highest percentage of individuals with migration intentions,\nwhile Haiti has the lowest")

## Bonus: Reverse Variables

According to the LAPOP Editorial Guidelines, when variables are measured on a scale, reversing them can enhance clarity and coherence in data representation. For instance, if a survey question aims to measure positive sentiment but higher numeric values indicate negative responses, reversing the variable aligns the coding with the expected direction of responses. This makes it easier for readers to understand the findings.

    # For data.frames
    cm23$ing4r <- lpr_resc(cm23$ing4, reverse = TRUE, map=TRUE)
