风玫瑰图与ggplot [英] Wind rose chart with ggplot
本文介绍了风玫瑰图与ggplot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
我试图使用来自Andy Clifton的梦幻风玫瑰R代码，它的 https://stackoverflow.com/a/17266781/ 709777 ，用于绘制从气象模型中提取的数据。从模型中，我可以得到u和v风分量，单位为m / s。然后我计算风速和风向并尝试风玫瑰码。但我不确定它是否按预期工作，或者我不明白该功能在做什么。
我尝试使用Andy的函数和以下代码来绘制4风玫瑰：
flist< -c（03050，12010，46070，46050）
for（i in 1：4）{
windfile = paste（viento - ，flist [i]，。csv，sep =）
viento = read.table（windfile，sep =;，header = F）
colnames（viento）< - c（u，v）
fecha = read.table （ffhh.txt，header = F，sep =;）
colnames（fecha）< -c（date，hr）
wind< -cbind .data.frame（fecha，viento）
wind $ speed = sqrt（wind $ u * wind $ u + wind $ v * wind $ v）
wind $ dir = windDir（wind $ u，wind $ v）
graf = paste（RAMS-wind-rose - ，flist [i]，。png，sep =）
png（graf ，res = 240，width = 3000，height = 2400）
plot.windrose（data = wind，spd =speed，dir =dir）
dev.off（）
$ / code> 图形输出是
因此最大风速在18-20米/秒范围内。这样对吗？但是，如果我寻找最大风速，我会得到不同的价值
pre $ max $ wind $ speed
[1] 10.24317
也许我误解了 wind.rose 函数运行，或者在调用函数时可能有问题。任何建议，将不胜感激，我现在卡在这里。

dir），row.names = c（NA， -170L），class =data.frame）
解决方案
原始函数中存在一个错误，如果最大速度未超过默认最大速度20，则数字中断点将转换为 1：n ，导致值不正确地落入标记较高的箱。
更改行 spd.breaks< - c（seq（spdseq））到 spd.breaks< - spdseq 。
在您的情况下，您还需要将 spdmax = 12 作为参数，所以你的图例没有unu sed值和 spdmin = 0 ，因为您的值低于默认最小值2。
结果在改变那行代码之后：
plot.windrose（data = wind，spd =speed，dir =dir，spdmin = 0，spdmax = 12）
I am trying to use the fantastic wind rose R code from Andy Clifton at https://stackoverflow.com/a/17266781/709777 for plotting data extracted from a meteorological model. From the model I get u and v wind components in m/s. Then I compute wind speed and direction and try wind rose code. But I'm not sure it is working as expected or maybe I don't understand what the function is doing.
My attempt uses Andy's function and the following code to plot 4 wind roses:
flist<-c("03050","12010","46070","46050")
for (i in 1:4 ) {
windfile=paste("viento-",flist[i],".csv",sep="")
viento=read.table(windfile,sep=";",header=F)
colnames(viento) <- c("u","v")
fecha=read.table("ffhh.txt",header=F,sep=";")
colnames(fecha) <- c("date","hr")
wind<-cbind.data.frame(fecha,viento)
wind$speed=sqrt(wind$u*wind$u+wind$v*wind$v)
wind$dir=windDir(wind$u,wind$v)
graf=paste("RAMS-wind-rose-",flist[i],".png",sep="")
png(graf,res=240,width=3000, height=2400)
plot.windrose(data = wind,spd = "speed",dir = "dir")
dev.off()
}
Graphical output is
So maximum wind speed is in the 18-20 m/s range from the plot. Is it right? But if I look for maximum wind speed I get a different value
max(wind$speed)

Maybe I'm misunderstanding how wind.rose function runs or maybe there is a problem when calling the function. Any suggestion would be appreciated, I'm stuck here now.

解决方案
There's a bug in the original function where if your max speed does not exceed the default max speed of 20, the numeric break points are converted to 1:n, causing values to incorrectly fall into higher-labeled bins.
Change the line spd.breaks <- c(seq(spdseq)) to spd.breaks <- spdseq.
In your case you'll also want to pass spdmax = 12 as an argument so your legend doesn't have unused values, and spdmin = 0 as you have values below the default min of 2.
Result after changing that line of code:
plot.windrose(data = wind,spd = "speed",dir = "dir", spdmin = 0, spdmax = 12)
