缩放X轴错误，需要帮助添加%&引用；GGR图中X轴的符号

我正在尝试将X轴从3缩放到5乘以0.5，但每当我尝试使用scale_X_continuous或discrete时，我都会得到以下错误：“X”的比例已经存在。为“X”添加另一个比例将替换现有的比例”。X轴一点也不改变

我做错了什么？我发现的所有示例都建议使用scale_x_continuous/discrete来更改缩放，但找不到任何替代方法

此外，如何将“%”符号添加到X轴中的值？提前多谢

这是我的密码：

ggplot() +
  ggtitle("Crime rate and unemployment rate relationship \nin regions with lower unemployment rate") +
  geom_point(aes(x = Unemployment.rate, y= Crime_occurrences, colour = Crime),
             size = 2, data = df) +
  xlab("Unemployment Rate (%)") +
  ylab("Crime Occurrences") +
  new_scale_color()+
  labs(linetype = "Crime") +
  scale_x_continuous(breaks = seq(from = 3, to = 5, by = 0.5))

这是dput（如果需要）：

谢谢

试试这个：

library(ggplot2)
library(ggnewscale)
#Code
ggplot() +
  ggtitle("Crime rate and unemployment rate relationship \nin regions with lower unemployment rate") +
  geom_point(aes(x = Unemployment.rate, y= Crime_occurrences, colour = Crime),
             size = 2, data = df) +
  scale_x_continuous(breaks = seq(from = 3, to = 5, by = 0.5),
                     limits = c(3,5),
                     labels = function(x) paste0(x,'%'))+
  xlab("Unemployment Rate (%)") +
  ylab("Crime Occurrences") +
  new_scale_color()+
  labs(linetype = "Crime")

输出：

更别致的选择（非常感谢并感谢@teunbrand）：

只需留下一条评论，说明scales软件包在这方面也有很好的功能。例如：

labels=scales:：percent_format（scale=1，精度=0.1）

@teunbrand我将把它添加到帖子中，非常感谢@非常感谢，我更新了你的信用卡。亲切的问候！一切都很好，谢谢大家！！
