我想在R中创建时间序列,但是我遇到了问题。我有30.07的风速数据。至02.09。每小时的分辨率。在x轴上应该是日期和时间,在y轴上应该是风速。我尝试了此脚本,但不幸的是它没有用。谁能帮帮我吗?这是我的代码:
options(stringsAsFactors = FALSE)
input1 <- "C:\\Users\\wind_speed.csv"
wind_speed <- read.csv(input1, sep=";")
dput(wind_speed)
library(ggplot2)
wind_speed$dateasdate <-gsub("\\.", "-", wind_speed$date)
wind_speed$dateasdate <- dmy(wind_speed$dateasdate)
wind_speed$date = as.Date(wind_speed$date, format = "%d.%m%.%y")
time <- strptime(wind_speed$time, format = "%H:%M:%S")
wind_speed$x <- paste(wind_speed$date,wind_speed$time)
timee2<- strptime(wind_speed$x, format= "%d.%m.%y %H:%M")
p <-ggplot(wind_speed, aes(x=x, y=speed)) + geom_point(stat="identity") +
geom_line(linetype="dashed")
print(p)
[时间序列应该看起来像图像,但x轴上带有日期和时间] [2]
这是我的数据示例:
head(wind_speed)
date time speed
1 27.07.2018 01:00:00 1.3
2 27.07.2018 02:00:00 0.8
3 27.07.2018 03:00:00 1.2
4 27.07.2018 04:00:00 0.6
5 27.07.2018 05:00:00 0.8
6 27.07.2018 06:00:00 1.8
