尝试在geom_sig
中运行ggplot
时遇到此错误。
Warning: Ignoring unknown aesthetics: xmin, xmax, annotations, y_position
Error in FUN(X[[i]], ...) : object 'Gender' not found
我的目标是在多面图中将重要指标放置在避开点周围。我尝试遵循尽可能接近软件包自述文件的方法,但是我无法克服此错误。
此代码复制了它。
library(tidyverse)
library(ggsignif)
set.seed(123)
df <- tibble(
Gender = c(rep('Female',15), rep('Male',15)),
key = paste(sample(LETTERS, 30, T), sample(1:30, 30, F), sep = '_'),
Value_mean = rnorm(30, 3, 1),
n = rep(100,30),
sd = rnorm(30, 1, .5),
se = rnorm(30, .05, .05),
lower.ci = Value_mean - se,
higher.ci = Value_mean + se,
trun_cat = rep(LETTERS[1:5], 6)
)
significant_df <- tibble(
trun_cat = c('A','C','E'),
start = c('H_29', 'R_24','L_23'),
end = start,
label = c('*', '**', '*'),
y = rep(4.5,3))
df %>%
ggplot(aes(
fct_reorder(key, Value_mean, .desc = T),
Value_mean,
group = Gender,
color = Gender,
fill = Gender
)) +
geom_errorbar(
aes(ymin = Value_mean - se,
ymax = Value_mean + se,),
width = .1,
position = position_dodge(0.5),
alpha = .9,
show.legend = F
) +
geom_point(
position = position_dodge(0.5),
size = 4,
show.legend = T,
alpha = 1
) +
geom_signif(
data = significant_df,
aes(
xmin = start,
xmax = end,
annotations = label,
y_position = y
),
textsize = 3,
vjust = -0.2,
manual = TRUE
)+
scale_color_grey() +
scale_fill_grey() +
facet_grid(~ trun_cat, scales = 'free_x')
如何解决该错误?
