R:如何绘制“时间序列"?与ggplot2 [英] R: how to plot a "time series" with ggplot2
本文介绍了R:如何绘制“时间序列"?与ggplot2的处理方法,对大家解决问题具有一定的参考价值,需要的朋友们下面随着小编来一起学习吧!
问题描述
我在R中模拟了一些时间序列数据,每8天汇总一次,然后尝试绘制结果.但是,这些图不起作用.我已经在下面发布了我的代码:
I simulated some time series data in R, aggregated by every 8 days, and then tried to plot the results. However, the plots are not working. I have posted my code below:
#load library
library(xts)
library(ggplot2)
set.seed(123)
#simulate data
property_damages_in_dollars <- rnorm(731,100,10)
date_decision_made = seq(as.Date("2014/1/1"), as.Date("2016/1/1"),by="day")
date_decision_made <- format(as.Date(date_decision_made), "%Y/%m/%d")
final_data <- data.frame(date_decision_made, property_damages_in_dollars)
#convert to xts object
dat <- xts(final_data$property_damages_in_dollars,
as.Date(final_data$date_decision_made, '%Y/%m/%d'))
#aggregate by 8 day period
ep <- endpoints(dat,'days',k=8)
a = period.apply(x=dat,ep,FUN=sum )
#plot : does not work
plot(a)
#plot using ggplot :does not work
ggplot(a, aes(x = a[,1], y=a$a))+
geom_line(aes(group=1))+
scale_x_discrete(guide = guide_axis(n.dodge=2))+
theme(axis.text.x = element_text(angle = 45))
有人可以告诉我我在做什么错吗?
Could someone please tell me what I am doing wrong?
谢谢
推荐答案
autoplot(a, geom = "point")
自动绘图似乎有效.更多信息
Autoplot seems to work. More info here.
