问题描述

我有一个数据框,我想从它生成一个 geom_tile()图,但我希望图的排序不是基于字母而是基于

  structure(list(V1 = c(a,y,w ,p,v,h,i),
V2 = c(r,w,q,m,l,q g),V3 = c(
5,2,9,2,1,3,0)),.Names = c(V1 ,V2,
V3),class =data.frame,row.names = c(NA,-8L))

我想根据变量 V3 命令图,因为正常绘图会根据字母排序在 V1 V2




解决方案

我通常会尝试使用关卡来修复我的数据:
$ (列表(V1)= c(a,y,w,p,v,h ,i),
V2 = c(r,w,q,m,l,q,g),V3 = c(
5 ,2,9,2,1,3,0)),.Names = c(V1,V2,
V3 =data.frame,row.names = c(NA,-8L))

x < - x [1:7,]

x $ V1 < - 因子(x $ V1,levels =(x $ V1)[order(x $ V3)])

#注意这不是一个有序的因子,它是正确顺序的一个因子

ggplot(x,aes(V1,V3))+ geom_tile()



更新:



仍然不完全清楚您的尺寸,但可能是这样的:

  x $ V2< ;  - 因子(x $ V2,levels =(x $ V2)[order(x $ V3)])

ggplot(x,aes(V1,V2,fill = V3))+ geom_tile )


i have a data frame and i want to generate a geom_tile() plot from it , but I want the graph to be ordered not based on the alphabetic but based on a variable inside this data frame.

structure(list(V1 = c("a", "y", "w", "p", "v", "h", "i"), 
    V2 = c("r", "w", "q", "m", "l", "q", "g"), V3 = c( 
    "5", "2", "9", "2", "1", "3", "0")), .Names = c("V1", "V2", 
"V3"), class = "data.frame", row.names = c(NA, -8L))

I want to order the plot based in the variable V3 , because the normal plotting will order them based on the alphabetic in V1 and V2 .

How this can be done ??

解决方案

I usually try to use levels to fix my data before hand:

x <- structure(list(V1 = c("a", "y", "w", "p", "v", "h", "i"), 
    V2 = c("r", "w", "q", "m", "l", "q", "g"), V3 = c( 
    "5", "2", "9", "2", "1", "3", "0")), .Names = c("V1", "V2", 
"V3"), class = "data.frame", row.names = c(NA, -8L))

x <- x[1:7,]

x$V1 <- factor(x$V1, levels=(x$V1)[order(x$V3)])

# Note it's not an ordered factor, it's a factor in the right order

ggplot(x, aes(V1, V3)) + geom_tile()

UPDATE:

Still not exactly clear on your dimensions, but perhaps something like:

x$V2 <- factor(x$V2, levels=(x$V2)[order(x$V3)])

ggplot(x, aes(V1,V2,fill=V3)) + geom_tile()
