[英]How to define width in error bars in ggplot2 (R)?
我有以下要绘制的数据。 我正在尝试更改错误栏的宽度,但遇到一个错误,提示Width not defined. Set with position_dodge(width = ?)
Width not defined. Set with position_dodge(width = ?)
。 我尝试做 position_dodge ..但它没有帮助。 有什么建议?
library(ggplot2)
time <- c("t1","t1","t1","t1","t1","t1","t2","t2","t2","t2","t2","t2")
species <- c(1,1,1,2,2,2,1,1,1,2,2,2)
value <- c(1,2,3,11,12,13,4,5,6,11,12,13)
df <- data.frame(time, species,value)
df$time <- as.factor(df$time)
df$species <- as.factor(df$species)
ggplot(df,aes(x=time, y=value, color = species, group = species)) + # Change fill to color
theme_bw() +
geom_point() +
stat_summary(fun.y=mean, position = "dodge") +
stat_summary(
geom="errorbar",
fun.data= mean_cl_boot,
width = 0.1, size = 0.2, col = "grey57") +
# Lines by species using grouping
stat_summary(aes(group = species), geom = "line", fun.y = mean) +
ylab("Fitness")
位置闪避用于在数据点重叠时显示所有数据点,我不确定这在您的示例中是否有任何用处,您可能会发现如果您的数据不重叠,只需删除此参数即可解决问题。 保持不变或者解决问题:
pd<-position_dodge(0.5)
ggplot(df,aes(x=time, y=value, color = species, group = species)) + # Change fill to color
theme_bw() +
geom_point(position = pd) +
stat_summary(fun.y=mean, position = pd) +
stat_summary(
geom="errorbar",
fun.data= mean_cl_boot,
width = 0.1, size = 0.2, col = "grey57",
position = pd) +
# Lines by species using grouping
stat_summary(aes(group = species), geom = "line", fun.y = mean, position = pd) +
ylab("Fitness")
