几个月前,我能够毫无错误地制作以下情节:
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)
现在这不再起作用了,我收到了错误
Error in eval(expr, envir, enclos) : Object 'count' not found
任何帮助我如何重新开始工作并解释为什么它不再起作用了? 谢谢!

答案 0 :(得分:1)
这似乎与公开问题有关
geom_hex不再识别2.1.0#1608中的..density ..
(Github)
似乎必须解决这个问题。
