我想制作一个热图,它创建一组清晰度为&的颜色组合作为X轴并切割为Y轴。热图将基于清晰度+颜色的计数以及其与切割的交点进行着色。Ggplot热图 - 用于定制计数范围的自定义颜色
library(ggplot2)
library(dplyr)
## rename diamonds df
# 1. Generate a count for the frequency of cut+clarity
# 2. Make a heatmap of this using the following bins
# 3. Red <= 100 Frequency
Yellow = between (100 and 500)
Green > 500
# place counts inside the cell:
df = diamonds %>%
select(cut, clarity) %>%
group_by(cut,clarity)%>%
mutate(count = n())
myplot = ggplot(df, aes(x = clarity, y=cut)) +
geom_bin2d(bins = c(100,500,50000), col='orange') #
geom_text(aes(label = count),col='red')
myplot
使用'切()'为 “离散化” 的连续变量,然后使用自定义比例指定这样你的颜色这样的问题:HTTP ://stackoverflow.com/questions/26103140/how-can-i-create-a-custom-colour-scale-using-ggplot2-and-geom-tile/26103786#26103786或这一个:http:// stackoverflow。 COM /问题/ 10981324/GGPLOT2-热图与 - 颜色换范围值/ 10982332#10982332。不要打扰geom_bin2d,这对分箱x和y值非常有帮助,但您已经有了离散值。 – MrFlick
