R中的3层甜甜圈图
R中的3层甜甜圈图
提问于 2022-08-12 12:08:18
我试图在R中重新创建这个图像，但是我无法想出如何将3层图层放到一个甜甜圈图中--我找到的所有东西(例如，webr::PieDonut)都只允许2层。使用ggplot，我也无法重新创建它。
A MRE是：
library(ggplot2)
library(webr)
library(dplyr)
lexicon <- data.frame("Level1" = c(rep("Flavour", 11), rep("Appearance", 4)),
"Level2" = c(rep("Misc", 6), rep("Pungent", 5), rep("Colour", 4)),
"Level3" = c("Fresh", "Refreshing", "Soapy", "Minty", "Nutty", "Milky", "Peppery", "Sharp", "Horseradish", "Mustard hot", "Spicy", "Colourful"," Fresh Green", "Dark Green", "Bright Green")
)
PieDonut(lexicon, aes(Level1, Level2), title = "Salad Lexicon", showRatioDonut =FALSE, showRatioPie = FALSE)
ggplot(lexicon, aes(Level2, Level3, fill = Level1)) +
geom_col() +
scale_fill_viridis_d() +
coord_polar("y")虽然PieDonut适用于2个级别(未显示)，但它不允许包含最终级别。如下图所示，ggplot方法也不起作用。
我怎样才能在R中得到这种风格的图表呢？无论是用ggplot还是基本绘图。

我认为一个很好的选择是在进行一些数据操作之后在这里使用geom_rect。使用填充、颜色和alpha标度可以帮助改善类别的差异。我也会在这里使用geom_textpath，不过，如果有这样做的余地，我可能会选择圆周标签：
lexicon %>%
mutate(top_level = Level1) %>%
pivot_longer(1:3) %>%
group_by(name, value) %>%
mutate(width = n()) %>%
unique() %>%
arrange(name) %>%
group_by(name) %>%
mutate(ymid = as.numeric(sub("\\D+", "", name)),
ymax = ymid + 0.5, ymin = ymid - 0.5,
xmin = c(0, head(cumsum(width), -1)),
xmax = cumsum(width),
xmid = (xmax + xmin) / 2) %>%
ggplot(aes(xmid, ymid, fill = top_level)) +
geom_rect(aes(xmin = xmin, xmax = xmax, ymin = ymin, ymax = ymax,
alpha = name, color = top_level)) +
geomtextpath::geom_textpath(aes(y = ymid + 0.25, label = value,
group = value)) +
scale_alpha_manual(values = c(1, 0.3, 0.1)) +
scale_fill_manual(values = c("#cd9900", "#00817e")) +
scale_colour_manual(values = c("#cd9900", "#00817e")) +
scale_y_continuous(limits = c(-0.5, 3.6)) +
coord_polar() +
theme_void() +
theme(legend.position = "none")

一种选择是将您的数据重组为long，并在传递到ggplot之前进行一些手动聚合。此外，我还使用geomtextpath::geom_textpath添加标签：
library(ggplot2)
library(dplyr)
library(geomtextpath)
lexicon <- data.frame("Level1" = c(rep("Flavour", 11), rep("Appearance", 4)),
"Level2" = c(rep("Misc", 6), rep("Pungent", 5), rep("Colour", 4)),
"Level3" = c("Fresh", "Refreshing", "Soapy", "Minty", "Nutty", "Milky", "Peppery", "Sharp", "Horseradish", "Mustard hot", "Spicy", "Colourful"," Fresh Green", "Dark Green", "Bright Green")
)
lexicon_long <- lexicon |>
mutate(fill = Level1) |>
tidyr::pivot_longer(-fill, names_to = "level", values_to = "label") |>
mutate(label = forcats::fct_inorder(label)) |>
count(fill, level, label) |>
group_by(level) |>
mutate(pct = n / sum(n))
ggplot(lexicon_long, aes(level, pct, fill = fill)) +
geom_col(color = "white") +
geom_textpath(aes(label = label, group = label),
position = position_stack(vjust = .5),
upright = TRUE, hjust = .5, size = 3
) +
scale_fill_viridis_d() +
coord_polar("y") +
theme_void() +
guides(fill = "none")
