英文:
Plotly showing NA for values in hover over
问题
我正在尝试将ggplot2图形转换为plotly图形，似乎工作正常，但悬停时显示Tumor_Volume变量的值为NA。它还显示组变量两次：悬停截图。
library(ggplot2)
library(plotly)
mouse_data$Mouse <- as.factor(mouse_data$Mouse)
mouse_data$Group <- as.factor(mouse_data$Group)
p <- ggplot(mouse_data, aes(x=Day, y=Tumor_Volume, color=Group,)) +
stat_summary(aes(group=Group), fun=mean, geom="line", size=1) +
stat_summary(aes(group=Group), fun=mean, geom="point", size=2) +
stat_summary(fun.data = mean_se, geom='errorbar', width=.5, size=0.7) +
theme_classic()
p
ggplotly(p)
不确定如何修复这个问题，有任何帮助吗？
EDIT：由于我忘记提供样本数据，请求样本数据的代码如下：
Mouse <- c(1, 1, 1, 2, 2, 2, 3, 3, 3, 4, 4, 4)
Group <- c('A','A','A','B','B','B','A','A','A','B','B','B')
Day <- c(1, 3, 5, 1, 3, 5, 1, 3, 5, 1, 3, 5)
Tumor_Volume <- c(1, 1.0829917, 1.2260616, 1, 1.1432288, 1.3644288,
1, 1.0551514, 1.3203255, 1, 1.3336704, 1.5578587)
Weight <- c(0, -1, -1, 0, 0, 1, 0, 0, 0, 0, 0, -1)
mouse_data <- data.frame(Mouse, Group, Day, Tumor_Volume)
Mouse是老鼠编号，总共有四只老鼠，有重复的测量值
Group是组变量，有两个组：A和B
Tumor_Volume是肿瘤体积，以1.00作为基线进行转换
Weight是标准化的体重值，以第1天为0，然后查看后续天数的体重变化
EDIT2：dput(mouse_data) 输出如下：（此部分文本太长，无法全部显示，请使用代码示例中的数据代替。）

I"m trying to convert a ggplot2 graph into a plotly graph, which seems to be working fine however the hover-over shows the values for the Tumor_Volume variable as NA. It also shows the group variable twice: Screenshot of hover-over.
library(ggplot2)
library(plotly)
mouse_data$Mouse <- as.factor(mouse_data$Mouse)
mouse_data$Group <- as.factor(mouse_data$Group)
p <- ggplot(mouse_data, aes(x=Day, y=Tumor_Volume, color=Group,)) +
stat_summary(aes(group=Group), fun=mean, geom="line", size=1) +
stat_summary(aes(group=Group), fun=mean, geom="point", size=2) +
stat_summary(fun.data = mean_se, geom='errorbar', width=.5, size=0.7) +
theme_classic()
p
ggplotly(p)
Not sure how to fix this, any help?
EDIT: Sample data requested due to me forgetting, apologies
Mouse <- c(1, 1, 1, 2, 2, 2, 3, 3, 3, 4, 4, 4)
Group <- c('A','A','A','B','B','B','A','A','A','B','B','B')
Day <- c(1, 3, 5, 1, 3, 5, 1, 3, 5, 1, 3, 5)
Tumor_Volume <- c(1, 1.0829917, 1.2260616, 1, 1.1432288, 1.3644288,
1, 1.0551514, 1.3203255, 1, 1.3336704, 1.5578587)
Weight <- c(0, -1, -1, 0, 0, 1, 0, 0, 0, 0, 0, -1)
mouse_data <- data.frame(Mouse, Group, Day, Tumor_Volume)
mouse is mouse number, four mice total with repeated measures
group is the group variable, two groups; A and B
tumor_volume tumor volume transformed with 1.00 as baseline
weight normalized weight values with day 1 at 0 and then looking at delta in weight for further days

`stat_summary`在内部计算汇总信息，所以在这种情况下（因为您正在使用`ggplotly(p)`并且想要显示汇总信息），我建议在绘图之前明确汇总，然后使用`geom_line`和`geom_point`代替`stat_summary`：
library(dplyr)
mouse_plot <- mouse_data %>%
summarize(TV_mean = mean(Tumor_Volume),
.by = c(Day, Group))
或者对于较旧版本的dplyr：
mouse_plot <- mouse_data %>%
group_by(Day, Group) %>%
summarize(TV_mean = mean(Tumor_Volume))
p <- ggplot(mouse_plot, aes(x = Day, y = TV_mean, color = Group)) +
geom_line(size = 1) +
geom_point(size = 2) +
theme_classic()
ggplotly(p)
或者不创建新数据集：
p <- mouse_data %>%
summarize(Tumor_Volume = mean(Tumor_Volume),
.by = c(Day, Group)) %>%
ggplot(aes(x=Day, y=Tumor_Volume, color=Group)) +
geom_line(size = 1) +
geom_point(size = 2) +
theme_classic()
ggplotly(p)
无论哪种方式，都可以获得以下结果：

英文:
stat_summary internally computes aggregates, so in this case (since you are using ggplotly(p) and want to show the aggregates) I would suggest explicitly summarizing before plotting, then using geom_line and geom_point instead of stat_summary:
library(dplyr)
mouse_plot <- mouse_data %>%
summarize(TV_mean = mean(Tumor_Volume),
.by = c(Day, Group))
## or for older versions of dplyr:
mouse_plot <- mouse_data %>%
group_by(Day, Group) %>%
summarize(TV_mean = mean(Tumor_Volume))
p <- ggplot(mouse_plot, aes(x = Day, y = TV_mean, color = Group)) +
geom_line(size = 1) +
geom_point(size = 2) +
theme_classic()
ggplotly(p)
Or without creating a new dataset:
p <- mouse_data %>%
summarize(Tumor_Volume = mean(Tumor_Volume),
.by = c(Day, Group)) %>%
ggplot(aes(x=Day, y=Tumor_Volume, color=Group)) +
geom_line(size = 1) +
geom_point(size = 2) +
theme_classic()
ggplotly(p)
