如何在 R 中使用时间序列数据制作热图

我一直在尝试使用 ggstruct 绘制热图。如果我能得到一些指示，我不介意使用基础图形。我希望热图看起来与此类似：

除了输入 ggstruct(df3) 然后抓耳挠腮之外，我没有再做任何事情了错误-这似乎是因为它不喜欢日期/时间数据？

这是两周数据样本的“dput”，间隔为 10 分钟。编辑：我的空间最终只够住 4 天。我希望这足够了。

非常感谢任何指点。

原文

I've been attempting to draw a heatmap using ggstructure. I don't mind using base graphics if I can get a few pointers. I want the heatmap to look similar to this:

http://www.vistadatavision.com/uploads/images/reports/intensity_plot_1.PNG

I haven't managed to get any further than typing ggstructure(df3) and then scratching my head at the error- which seems to be because it doesn't like the date/time data?

Here is the "dput" for a two week sample of the data, with 10 minute intervals.
edit: I only had enough room for 4 days worth in the end. I hope it'll suffice.

Any pointers much appreciated.

最偏执的依靠 2024-11-26 04:39:28

我正在使用 lubridate 包中的一些魔法将日期转换为 Date，然后提取月份和小时：

library(lubridate)

temp$lDate <- with(temp, ymd_hms(paste(date, time)))
temp$month <- month(temp$lDate)
temp$hour  <- hour(temp$lDate)

这里的关键是我使用了 lubridate 函数ymd_hms 从字符格式转换为日期格式。 lubridate提供了一系列方便的函数，使不同日期格式的转换变得非常容易，例如ymd、mdy等。

head(temp)

        date     time  speed               lDate month hour
1 2010-01-01 00:00:00  7.352 2010-01-01 00:00:00     1    0
2 2010-01-01 00:10:00  8.750 2010-01-01 00:10:00     1    0
3 2010-01-01 00:20:00  8.670 2010-01-01 00:20:00     1    0
4 2010-01-01 00:30:00  9.870 2010-01-01 00:30:00     1    0
5 2010-01-01 00:40:00 10.220 2010-01-01 00:40:00     1    0
6 2010-01-01 00:50:00  8.390 2010-01-01 00:50:00     1    0

然后就很简单了使用 ggplot 进行绘图：

ggplot(temp, aes(x=hour, y=month)) + geom_tile(aes(fill=speed))

在此处输入图像描述

I am using some of the magic in package lubridate to convert your date to Date, and then I extract the month and hour:

library(lubridate)

temp$lDate <- with(temp, ymd_hms(paste(date, time)))
temp$month <- month(temp$lDate)
temp$hour  <- hour(temp$lDate)

The key here is that I used the lubridate function ymd_hms to convert from character format into Date format. lubridate provides a range of convenience functions that makes conversions of different date format very easy, e.g. ymd, mdy, etc.

head(temp)

        date     time  speed               lDate month hour
1 2010-01-01 00:00:00  7.352 2010-01-01 00:00:00     1    0
2 2010-01-01 00:10:00  8.750 2010-01-01 00:10:00     1    0
3 2010-01-01 00:20:00  8.670 2010-01-01 00:20:00     1    0
4 2010-01-01 00:30:00  9.870 2010-01-01 00:30:00     1    0
5 2010-01-01 00:40:00 10.220 2010-01-01 00:40:00     1    0
6 2010-01-01 00:50:00  8.390 2010-01-01 00:50:00     1    0

Then it's straight-forward to plot using ggplot:

ggplot(temp, aes(x=hour, y=month)) + geom_tile(aes(fill=speed))
