[英]Reverse colors from ggmap points
I want to reverse the color of the points and the label from the following ggmap creation:我想从以下 ggmap 创建中反转点和 label 的颜色:
ggmap(Map) +
geom_point(data = DF, aes (x = Longitude,
y = Latitude,
color = RPM)) +
labs(y = "Latitude", x = "Longitude", color = "RPM")
I wouldn't like to change by now the data set to spatial points.我现在不想将数据集更改为空间点。
I'm getting the following result:我得到以下结果:
I have tried the following addition to the code presented:我已尝试对所提供的代码进行以下添加:
scale_colour_brewer(direction = -1)
But I'm getting the following error message:但我收到以下错误消息:
Error: Continuous value supplied to discrete scale错误:提供给离散刻度的连续值
Found the answer at: Reversing default scale gradient ggplot2在以下位置找到答案: 反转默认比例梯度 ggplot2
Simply switched place with the found R color default pallete for the case:只需使用找到的 R 颜色默认调色板切换位置即可:
scale_fill_continuous(high = "#132B43", low = "#56B1F7")
