嗨,我想用 R 脚本创建一个类似的图表,如下所示:
取自:https://community.tableau.com/thread/194440
这是我在 R 中的代码:
library(ggplot2)
ifile <- read.table("C:/ifiles/test.txt", skip = 2, header = TRUE, sep="\t")
ifileVI <- data.frame(ifile["VI"], ifile["Site"])
x<-quantile(ifileVI$VI,c(0.01,0.99))
data_clean <- ifileVI[bfileVI$VI >=x[1] & ifileVI$VI <=x[2],]
p <- ggplot(data_clean, aes(x = Site, y = VI, group=Site)) + geom_boxplot() + geom_histogram(binwidth = 0.05)
p
但是我收到以下错误:
Error: stat_bin() must not be used with a y aesthetic.
文件VI:
Id VI Site

最佳答案
您可以尝试用矩形替换直方图以生成如下图:
这该怎么做:
生成随机数据
df <- data.frame(State = LETTERS[1:3],
Y = sample(1:10, 30, replace = TRUE),
X = rep(1:10, 3))
用矩形替换直方图
library(ggplot2)
# You can plot geom_histogram or bar (pre-counted stats)
ggplot(df, aes(X, Y)) +
geom_bar(stat = "identity", position = "dodge") +
facet_grid(State ~ .)
# Or you can plot similar figure with geom_rect
ggplot(df) +
geom_rect(aes(xmin = X - 0.4, xmax = X + 0.4, ymin = 0, ymax = Y)) +
facet_grid(State ~ .)
添加箱线图
要添加箱线图,我们需要:
coord_flip
) geom_rect
代码:
ggplot(df) +
geom_rect(aes(xmin = 0, xmax = Y, ymin = X - 0.4, ymax = X + 0.4)) +
geom_boxplot(aes(X, Y)) +
coord_flip() +
facet_grid(State ~ .)
结果:
具有更好视觉效果的最终绘图代码
ggplot(df) +
geom_rect(aes(xmin = 0, xmax = Y, ymin = X - 0.4, ymax = X + 0.4),
fill = "blue", color = "black") +
geom_boxplot(aes(X, Y), alpha = 0.7, fill = "salmon2") +
coord_flip() +
facet_grid(State ~ .) +
theme_classic() +
scale_y_continuous(breaks = 1:max(df$X))
