[英]plot TOTAL errorbar for multiple lines in ggplot r
I would like to plot the data by subject but adding the errorbar of the total mean and se.我想按主题 plot 数据,但添加总平均值和 se 的误差线。 I mean, not an error bar for each subject.
我的意思是,不是每个主题的错误栏。 I've tried geom_errorbar and stat_summary but still failed to get my ideal plot (see the figure I drew).
我已经尝试过 geom_errorbar 和 stat_summary 但仍然未能得到我理想的 plot(参见我画的图)。
and here is the code I used to draw this figure (the errorbars are added by hand).这是我用来绘制此图的代码(错误栏是手动添加的)。
ggplot(ASD, aes(x=period, y=meanF0, group=subject, color=group)) +
geom_line(aes(color=group, size=group)) +
scale_size_manual(values=c(.6, .6, .6, .6)) +
theme_light()+
xlab("Period")+
ylab("F0 (Hz)")+
ggtitle("Mean F0 Adjustment (ASD Group)") +
geom_point()+
scale_color_manual(values=c("red")) +
theme(plot.title = element_text(size=14.5, face="bold", hjust = 0.5, family = "serif"),
axis.title.y= element_text(size=12, face = "bold", family = "serif"),
axis.title.x= element_text(size=12, face = "bold", family = "serif"),
axis.text.x = element_text(size=11, face="bold", family = "serif"),
axis.text.y = element_text(size=11, face="bold", family = "serif"))+
theme(legend.position = "none")+
geom_hline(yintercept=112.8, linetype="dashed",
color = "dark grey", size=.7)
Anyone could help?任何人都可以帮忙吗? Thank you very much!!!
非常感谢!!!
Use annotate
to add the error bars.使用
annotate
添加误差线。 I don't have your data, so I created my own.我没有你的数据,所以我创建了自己的。 You're going to need the confidence interval and the average for each group.
您将需要每个组的置信区间和平均值。 My average-by-group values and confidence interval-by-group are stored in
df4$meanV
and df4$ci
.我的按组平均值和按组置信区间存储在
df4$meanV
和df4$ci
中。 You can replace these with your variable names.您可以将这些替换为您的变量名称。 In annotate, you'll include the data frame in the call like you would in base R plots.
在注释中,您将在调用中包含数据框,就像在基本 R 图中一样。 Like base R, you can just use raw values, as well.
与基础 R 一样,您也可以只使用原始值。 Multiple values can be joined with
c()
.可以使用
c()
连接多个值。 As in y = c(12, 10)
.如
y = c(12, 10)
。 If you have any questions, just let me know.如果您有任何问题,请告诉我。
ggplot(df2, aes(x = condition, y = value,
color = subject, group = subject)) +
geom_line() + geom_point() +
annotate("errorbar",
x = df4$condition
ymin = df4$meanV - df4$ci,
ymax = df4$meanV + df4$ci,
width = .2) +
annotate("point",
x = df4$condition,
y = df4$meanV) +
ylim(min(df2$value), max(df2$value))
