为R中的不同点集设置自己的颜色和形状比例

我试图在一个绘图中绘制两组点，我希望每个点都有自己的颜色比例和形状比例。当我添加第二个颜色比例和形状比例时，第一个颜色和形状比例被替换

我的目标是，每个点集都有自己的图例，显示其颜色和形状

我的数据帧（

df

）如下所示：

variable measurements set1 set2
a        1            2    3
a        2            3    4
b        3            4    5
b        4            5    6
c        5            6    7
c        6            7    8    
d        7            8    9
d        8            8    10
e        9            10   11
e        10           11   12

这是我的密码：

p<-ggplot()+
  geom_point(data = df,aes(x = measurements,y = set1,shape=variable),colour="red",size=3)+
  #scale_shape_manual(name="set1",
  #                   labels=c("A","B","C","D","E"),
  #                   values = c(0, 1, 2, 4, 8)) +
  #scale_colour_manual(name="set1",
  #                    labels=c("A","B","C","D","E"),
  #                    values = c("red", "red", "red", "red","red")) +
  geom_point(data = df,aes(x = measurements,y = set2,shape=variable), colour="green",size=3)+
  #scale_shape_manual(name="set2",
  #                   labels=c("A","B","C","D","E"),
  #                   values = c(22, 16, 24, 23, 11)) +
  #scale_colour_manual(name="set2",
  #                    labels=c("A","B","C","D","E"),
  #                    values = c("green", "green", "green", "green","green"))

p您需要将数据转换成不同的格式
试试这个


我可能会补充你，你可能想做方面

ggplot(rookie.df.m, aes(x=factor(measurements), y = value, shape = variable)) +geom_point()+ 
    scale_fill_manual(values = c("set1" = "red","set2" = "green"))+scale_shape(solid = FALSE)+theme_bw() +facet_wrap(~group)

下面是情节：

或者改为在组“变量”上刻面（我最喜欢这个，因为它可以让您轻松地看到度量值是如何聚集的）

    ggplot(rookie.df.m, aes(x=factor(measurements), y = value, 
    shape = variable)) +
    geom_point(aes(colour = group)) +
    scale_fill_manual(values = c("set1" = "red","set2" = "green")) +
    scale_shape(solid = FALSE) + theme_bw() +facet_wrap(~variable)

谢谢您的回复。
ggplot（rookie.df.m，aes（x=测量值，y=值，shape=变量））
对我来说非常合适。但我遇到了另一个问题，那就是如何更改两个图例的名称、两个图例的关键名称以及两个图例的相对位置。不客气。这里有一个参考资料，您好，您非常擅长使用R，我将仔细阅读链接。@infominer，如何为每个gro添加
geom_smooth
向上的
ggplot(rookie.df.m, aes(x=factor(measurements), y = value, shape = variable)) +geom_point()+ 
    scale_fill_manual(values = c("set1" = "red","set2" = "green"))+scale_shape(solid = FALSE)+theme_bw() +facet_wrap(~group)

    ggplot(rookie.df.m, aes(x=factor(measurements), y = value, 
    shape = variable)) +
    geom_point(aes(colour = group)) +
    scale_fill_manual(values = c("set1" = "red","set2" = "green")) +
    scale_shape(solid = FALSE) + theme_bw() +facet_wrap(~variable)
