ggplot2を使用したExcelグラフィック

Excelの疑似3Dグラフは問題でいっぱいだということには誰もが同意していると思いますが、給料に署名する人と妥協しなければならない状況には共感します。

また、もっと趣味が必要です。

ステップ1.データ（つまり通常のもの）のロードと再形成：

library(dplyr); library(tidyr)

# original data as provided by OP
gender <- c("Male", "Male", "Female", "Male", "Male", "Female", "Male", "Male", "Female", "Male", 
            "Male", "Female")
race <- c("African American", "Caucasian", "Hispanic", "African American", "African American", 
          "Caucasian", "Hispanic", "Other", "African American", "Caucasian", "African American", 
          "Other")
data <- as.data.frame(cbind(gender, race))

# data wrangling
data.gather <- data %>% gather() %>%
  group_by(key, value) %>% summarise(count = n()) %>%
  mutate(prop = count / sum(count)) %>% ungroup() %>%
  mutate(value = factor(value, levels = c("Male", "Female", "African American",
                                          "Caucasian", "Hispanic", "Other")),
         value.int = as.integer(value))

rm(data, gender, race)

ステップ2.3Dエフェクトバー（つまり、歯ごたえのあるもの）のポリゴン座標を定義します。

# top
data.polygon.top <- data.gather %>%
  select(key, value.int, prop) %>%
  mutate(x1 = value.int - 0.25, y1 = prop,
         x2 = value.int - 0.15, y2 = prop + 0.02,
         x3 = value.int + 0.35, y3 = prop + 0.02,
         x4 = value.int + 0.25, y4 = prop) %>%
  select(-prop) %>%
  gather(k, v, -value.int, -key) %>%
  mutate(dir = str_extract(k, "x|y")) %>%
  mutate(k = as.integer(gsub("x|y", "", k))) %>%
  spread(dir, v) %>%
  rename(id = value.int, order = k) %>%
  mutate(group = paste0(id, ".", "top"))

# right side
data.polygon.side <- data.gather %>%
  select(key, value.int, prop) %>%
  mutate(x1 = value.int + 0.25, y1 = 0,
         x2 = value.int + 0.25, y2 = prop,
         x3 = value.int + 0.35, y3 = prop + 0.02,
         x4 = value.int + 0.35, y4 = 0.02) %>%
  select(-prop) %>%
  gather(k, v, -value.int, -key) %>%
  mutate(dir = str_extract(k, "x|y")) %>%
  mutate(k = as.integer(gsub("x|y", "", k))) %>%
  spread(dir, v) %>%
  rename(id = value.int, order = k) %>%
  mutate(group = paste0(id, ".", "bottom"))

data.polygon <- rbind(data.polygon.top, data.polygon.side)
rm(data.polygon.top, data.polygon.side)

ステップ3.それをまとめる：

ggplot(data.gather,
       aes(x = value.int, group = value.int, y = prop, fill = key)) +

  # "floor" of 3D panel
  geom_rect(xmin = -5, xmax = 10, ymin = 0, ymax = 0.02,
            fill = "grey", color = "black") +

  # background of 3D panel (offset by 2% vertically)
  geom_hline(yintercept = seq(0, 1, by = 0.2) + 0.02, color = "grey") +

  # 3D effect on geom bars
  geom_polygon(data = data.polygon,
               aes(x = x, y = y, group = group, fill = key),
               color = "black") +

  geom_col(width = 0.5, color = "black") +
  geom_text(aes(label = scales::percent(prop)),
            vjust = -1.5) +
  scale_x_continuous(breaks = seq(length(levels(data.gather$value))),
                     labels = levels(data.gather$value),
                     name = "", expand = c(0.2, 0)) +
  scale_y_continuous(breaks = seq(0, 1, by = 0.2),
                     labels = scales::percent, name = "",
                     expand = c(0, 0)) +
  scale_fill_manual(values = c(gender = "#5f1b46",
                               race = "#3b6b74"),
                    guide = F) +
  facet_grid(~key, scales = "free_x", space = "free_x") +
  theme(panel.spacing = unit(0, "npc"), #remove spacing between facets
        strip.text = element_blank(), #remove facet header
        axis.line = element_line(colour = "black", linetype = 1),
        panel.grid.major = element_blank(),
        panel.grid.minor = element_blank(),
        panel.background = element_rect(fill = '#f9f3e5'),
        plot.background = element_rect(fill = '#f9f3e5'))

注：geom_rect()/ geom_hline()/ geom_polygon()geomsをコメントアウトし、ファセット間隔/ヘッダーを非表示にするのをやめるとtheme()、これはほとんど見栄えがします...
