Geom_smooth没有出现在简单图中 [英] Geom_smooth not appearing in simple plot

问题描述

ggplot(R3L12, aes(x=Time, y=HeartRate)) +
  geom_point() +
  geom_smooth()

这是dput(head(R3L12，20))的输出

This is the output of dput(head(R3L12, 20))

structure(list(Date = c("2015-05-23", "2015-05-23", "2015-05-23", 
"2015-05-23", "2015-05-23", "2015-05-23", "2015-05-23", "2015-05-23", 
"2015-05-23", "2015-05-23", "2015-05-23", "2015-05-23", "2015-05-23", 
"2015-05-23", "2015-05-23", "2015-05-23", "2015-05-23", "2015-05-23", 
"2015-05-23", "2015-05-23"), Time = c("07:25:00", "07:40:00", 
"07:45:00", "09:10:00", "11:45:00", "11:55:00", "12:05:00", "12:35:00", 
"12:45:00", "13:30:00", "13:40:00", "13:45:00", "13:55:00", "14:00:00", 
"14:05:00", "14:10:00", "14:20:00", "14:25:00", "14:30:00", "14:35:00"
), Turtle = structure(c(3L, 3L, 3L, 3L, 3L, 3L, 3L, 3L, 3L, 3L, 
3L, 3L, 3L, 3L, 3L, 3L, 3L, 3L, 3L, 3L), .Label = c("R3L1", "R3L11", 
"R3L12", "R3L2", "R3L4", "R3L8", "R3L9", "R4L8", "R8L1", "R8L4", 
"R8NAT123"), class = "factor"), HeartRate = c(7.56457, 6.66759, 
17.51107, 9.72277, 19.44553, 13.07674, 28.115, 14.99467, 17.16947, 
40.40479, 37.76642, 29.98933, 43.5329, 49.61471, 47.74245, 44.10196, 
21.35316, 44.68609, 49.25255, 29.98933)), row.names = c(NA, 20L
), class = "data.frame")

这是我尝试创建的绘图的代码.我很困惑，因为当我绘制它时，geom_smooth不会显示. Time 是一个因子变量，而 HeartRate 是一个double.我是R的新手，所以如果您需要更多信息，请告诉我！

Here is the code of a plot I tried to create. I'm confused because when I plot it, the geom_smooth doesn't show up. Time is a factor variable, and HeartRate is a double. I'm new to R so let me know if you need more information!

推荐答案

使用 lubridate 包的替代解决方案:

An alternative solution using lubridate package:

library(lubridate)
library(scales)
library(dplyr)
library(ggplot2)
df %>% 
  mutate(DateTime = ymd_hms(paste(Date, Time))) %>%
  ggplot(aes(x= DateTime, y = HeartRate))+
  geom_point()+
  geom_smooth()+
  scale_x_datetime( breaks=date_breaks("1 hour"), labels = date_format("%H:%M"))
