r - R散点图ylim错误NA值

Question

我正在尝试将我在 excel 中制作的图表重新创建到 R 中。这是图表的 excel 版本...

http://i.imgur.com/FJXbLy8.png

我的数据集分为 5 个部分。为简单起见，我将 x 和 y 标签称为时间和距离。我想在形状图表上绘制 5 辆“汽车”。

包含数据的 CSV 文件如下所示（不是实数！）：

A       B       C      D      E      F     ...
1       4       1      8      7      15
3       5       5      10     12     20
5       6       7      14     20     40

其中 (A, B) 为您提供 1 号车的时间/距离，(C, D) 为您提供 2 号车的时间/距离， (E, F) 为您提供 3 号车的时间/距离，依此类推。

我的代码如下所示：

speed = read.csv (file = "c:/users/XXX/desktop/speed", header = TRUE, sep = ',')
plot (A ~ B, data = speed, xlim = range (1e-5:100), ylim = range (0:200), log = "x")     
par(new = TRUE) 
plot (C ~ D, data = speed, xlim = range (1e-5:100), ylim = range (0:200), log = "x") 
par (new = TRUE)
plot (E ~ F, data = speed, xlim = range (1e-5:100), ylim = range (0:200), log = "x") 
par(new = TRUE )
plot(G ~ H, data = speed, xlim = range (1e-5:100), ylim = range (0:200), log = "x") 
par (new = TRUE) 
plot(I ~ J, data = speed, xlim = range (1e-5:100), ylim = range (0:200), log = "x")

我收到一条错误消息，说我的 ylim 值无效...我尝试更改数字但没有运气。

任何提示将不胜感激！

如果它对任何人都有帮助... - 我注意到 dput 中的 NA 值，我认为这dput(speed)是因为并非每个“汽车”的每个数据集都不相等？不知道如何解决这个问题...我可以将每个“汽车”的每个数据集放入不同的文件中，这样会更好吗？

Answer 1

我不确定你在看什么。我认为这可能会有所帮助。

speed <- structure(list(A = c(3.59e-05, 3.75e-05, 9.67e-05, 3.92e-05,
  2.14e-05, 9.8e-05, 0.000228481, 0.000228481, 0.000415583, 0.000859052,

 NA, NA, NA, NA, NA, NA ), I = c(0.021, 0.0258, 0.029929032, 0.034574194, 
0.064612903,   0.088870968, 0.17816129, 0.163967742, NA, NA, NA, NA, NA,

.Names = c("A", "B", "C", "D", "E", "F", "G", "H", "I", "J"),
 class = "data.frame", row.names = c(NA, -23L))

使用基础 R

绘图

plot(speed$A,speed$B,xlim=range(1e-5:100),ylim=range(0:200),xlab="Time",ylab="Distance",pch=19,log="x")
points(speed$C,speed$D,col="red",pch=21)
points(speed$E,speed$F,col="blue",pch=18)
points(speed$G,speed$H,col="yellow",pch=19)
points(speed$I,speed$J,col="green",pch=20)
legend("top", legend = c("Car 1","Car 2","Car 3","Car 4","Car 5"), col = c("black","red","blue","yellow","green"),
       ncol = 2,pch=c(19,21,18,19,20))

输出图如下：

使用 ggplot2 ggplot2 的选项会自动删除具有缺失值的点。

library(ggplot2)
ggplot(speed,aes(A,B))+geom_point()+xlim(1e-5,100)+ylim(0,200)+scale_x_log10()+
  geom_point(data=speed,aes(C,D),col="red")+geom_point(data=speed,aes(E,F),col="blue")+
  geom_point(data=speed,aes(G,H),col="green")+geom_point(data=speed,aes(I,J),col="orange",shape=2)+
  xlab("Distance")+ylab("Distance")

使用长格式数据和 ggplot2 的另一个选项

## Separate the data by cars
car1 <- speed[,c(1,2)]
car1$id <- "Car1"
car2 <- speed[,c(3,4)]
car2$id <- "Car2"
car3 <- speed[,c(5,6)]
car3$id <- "Car3"
car4 <- speed[,c(7,8)]
car4$id <- "Car4"
car5 <- speed[,c(9,10)]
car5$id <- "Car5"
names(car1)<- names(car2) <- names(car3) <- names(car4) <- names(car5)<- c("distance","speed","id")

合并数据集

myspeed <- rbind(car1,car2,car3,car4,car5)

用图例绘制 ggplot

ggplot(myspeed,aes(distance,speed))+geom_point(aes(color=id))+xlim(1e-5,100)+ylim(0,200)+scale_x_log10()

输出如下：
