ggplot2错误：创建渐变贴图时将离散值提供给连续刻度
[英]ggplot2 Error: Discrete value supplied to continuous scale when creating gradient map
问题描述
This has been asked before but I can't get any previous solutions to work.
之前已经有人问过这个问题，但我无法获得以前的任何解决方案。
I am trying to create a map (works) which colours on a gradient according to the data set I'm feeding into it (doesn't work).我正在尝试创建一个地图（有效），该地图根据我要输入的数据集在渐变上进行着色（不起作用）。
Currently I have the following目前我有以下
plot1 <- ggplot(map, aes(x=long, y = lat, group = group, fill = map$`data`)) + geom_polygon(colour="white") + coord_map("polyconic")
plot1 <- plot1 + ggtitle("Data")
plot1 <- plot1 + scale_fill_gradient2(low = "#559999", mid = "grey", high = "#BB650B")
My data set is currently set up as the following我的数据集当前设置如下
map region: chr, long: num, lat: num, group: num, order: int, data: num地图区域：hr，long：num，lat：num，group：num，order：int，data：num
Any ideas?有任何想法吗？
