r - ggplot() 没有预期的数字

问题描述

我有一个数据框 StatMNS统计信息系统我在不同区域 (x) 上为每种类型的 MNS（颜色）绘制统计数据 (y)

ggplot(statMNS,aes(x=1:n))+
geom_point(aes(y=as.numeric(statMNS$v1qu_lidar)),size=2,col="skyblue")+
geom_point(aes(y=as.numeric(statMNS$v1qu_photo)),size=2,col="tan")+
geom_point(aes(y=as.numeric(statMNS$v3qu_lidar)),size=2,col="slateblue")+
geom_point(aes(y=as.numeric(statMNS$v3qu_photo)),size=2,col="tan3")+
geom_point(aes(y=as.numeric(statMNS$vmax_lidar)),size=2,col="navyblue")+
geom_point(aes(y=as.numeric(statMNS$vmax_photo)),size=2,col="tan4")+
geom_point(aes(y=as.numeric(statMNS$vmean_lidar)),size=2,col="skyblue4")+
geom_point(aes(y=as.numeric(statMNS$vmean_photo)),size=2,col="tan2")+
...+
labs(title = "Stat placette\n", x = "Placette", y = "Hauteur (m)", color = "Legend Title\n") +
scale_color_manual(values=c("max lidar"="navyblue", "max photo"="tan4",
                          "3e qu. lidar"="slatebule","3e qu. phot"="tan3",
                          "moy lidar"="skyblue4", "moy photo"="tan2",
                          "mediane lidar"="skyblue3","mediane photo"="tan1",
                          "1r qu. lidar"="skyblue","1r qu. photo"="tan",
                          "min lidar"="powderblue", "min photo"="lightgoldenrod1") )


statMNS2 <- gather(data = statMNS,key = TYPE,value = VAL,vmax_lidar,vmax_photo,v3qu_lidar,v3qu_photo,vmean_lidar,vmean_photo,vmedian_lidar,vmedian_photo,v1qu_lidar,v1qu_photo,vmin_lidar,vmin_photo)

ggplot(statMNS2,aes(statMNS2$readerName,VAL),color=TYPE)+geom_point()`

首先，我想显示图例其次，我想将 x 向量 1:n 替换为区域名称（dataFrame 的列 readerName）

我尝试在 StatMNS2 中重新排列我的数据，
StatMNS2
但出现错误（提供给连续刻度的离散值）

dput(statMNS)
structure(list(readerName = structure(list(X1 = "LBO_1", X2 = "LBO_11",

谢谢你的帮助

解决方案

由于您没有提供示例数据，因此很难重现您想要的内容。但是，我想您的问题在于屏幕截图的最后一行，因为您可以保留color在其中，aes()并且只需要readerName而不是statMNS2$readerName.

我使用了一些示例数据使其工作，并为您提供了一个可能适用于您的数据的示例。

library(ggplot2)

# sample data
ggplot(ToothGrowth, aes(x=supp, y=len, color=dose))+
  geom_point(size=2)

# try on your data
statMNS2$VAL <- as.numeric(statMNS2$VAL)
ggplot(statMNS2, aes(x=readerName, y=VAL, color=TYPE))+
  geom_point(size=2)

它会给你预期的结果吗？

编辑：使用简短版本的数据时，一切正常。这个例子对你有用吗？启动一个新的 R-Session，复制并粘贴下面的整个代码，看看它是否有效。

# short version of your data
statMNS2 <- data.frame(readerName = c("LBO_1", "LBO_11", "LBO_12", 
                          "LBO_13", "LBO_2", "LBO_3", "LBO_4", "LBO_5", "LBO_6", "LBO_7", 
                          "LBO_1", "LBO_11", "LBO_12", "LBO_13", "LBO_2", "LBO_3", 
                          "LBO_4", "LBO_5", "LBO_6", "LBO_7"),
           TYPE = c("vmax_lidar", "vmax_photo", "v3qu_lidar", 
                    "v3qu_photo", "vmean_lidar", "vmean_photo", "vmean_photo",  
                    "vmedian_lidar", "vmedian_photo", "v1qu_lidar","v1qu_photo", 
                    "vmin_lidar", "vmin_photo", "vmin_photo", "vmin_photo", "vmin_photo", 
                    "vmin_photo", "vmin_photo", "vmin_photo", "vmin_photo"), 
           VAL = c(
             167.4, 159.1, 163.5, 163.4, 160, 158.9, 153.8, 151, 157.3, 
             155.8, 148.8, 157.5, 161.1, 161.7, 158.1, 150.8, 141.6, 147.1, 
             155.1, 151.4))

# same ggplot call as above
library(ggplot2)
ggplot(statMNS2, aes(x=readerName, y=VAL, color=TYPE))+
  geom_point(size=2)
