ggplot2：..count ..不再与stat_bin_hex一起工作 [英] ggplot2: ..count.. not working with stat_bin_hex anymore

问题描述

几个月前，我能够无误地生成以下图：

  library（ggplot2）
 library （十六进制）
x < -  rnorm（100）
y < -  rnorm（100，mean = 2）
 ggplot（data = data.frame（x，y））+ stat_bin_hex（aes （x = x，y = y，alpha = .. count ..），fill =＃ED1A3A，bins = 10）
  

现在这不再起作用了，我得到错误

  eval中的错误（expr，envir ，enclos）：找不到对象'count'
  

任何帮助我如何重新开始工作并解释为什么它不再工作了？
谢谢！

这似乎与未决问题有关

geom_hex不再识别..density .. in 2.1.0＃1608

（ Github ）

似乎必须修复，但是。

Some months ago I was able to produce the following plot without errors:

library(ggplot2)
library(hexbin)
x <- rnorm(100)
y <- rnorm(100, mean=2)
ggplot(data = data.frame(x,y)) +  stat_bin_hex(aes(x=x, y=y, alpha=..count..), fill="#ED1A3A", bins=10) 

Now this does not work anymore and I get the error

Error in eval(expr, envir, enclos) : Object 'count' not found

Any help how I get this working again and explanation why its not working anymore? Thanks!

EDIT 2: Interestingly it still works with stat_bin_2d.

解决方案

This seems to be related to the open issue

geom_hex no longer recognizes ..density.. in 2.1.0 #1608

(Github)

that seems to have to fix, yet.
