st_normalize.sfc(x，c(x_range [1]，y_range [1]，x_range [2]，y_range [2])中的错误:域必须具有正范围 [英] Error in st_normalize.sfc(x, c(x_range[1], y_range[1], x_range[2], y_range[2])) : domain must have a positive range

问题描述

背景:

我正在使用ggplot2 geom_point按周映射动物位置点.作为底图，我正在使用计算机中的shapefile.

I am using ggplot2 geom_point to map animal location points by week. As a basemap, I am using a shapefile from my computer.

以下是我的数据示例:

datexample <- data.frame(
  "animal" = c("A","B"), 
  "yearweek" = c(202028, 202028, 202029, 202029),
  "lat" =  c(45.25, 44.75, 45.25, 45.75), 
  "lon" = c(-61.75, -61.25, -62.75, -62.25)
)
datexample

以下是不添加底图的ggplot的示例:

Here is an example of the ggplot without the basemap added:

geom_point(data = dat, aes(x = lon, y = lat, alpha = yearweek))+
  facet_grid(cols = vars(animal)) +
  xlab("Longitude")+
  ylab("Latitude")

问题:

在我将R和RStudio更新到最新版本(上周)之前，上面的代码起作用了.现在，这些地图将不会绘制，并且出现以下错误:

The above code worked before I updated R and RStudio to the newest version (last week). Now, these maps will not draw, and I get the following error:

Error in st_normalize.sfc(x, c(x_range[1], y_range[1], x_range[2], y_range[2])) : domain must have a positive range 

我尝试过的事情:

• 重新启动R和RStudio
• 重新安装并更新了ggplot2和dplyr

我尚未将shapefile移动到计算机上的另一个文件夹中，并且它们已正确导入到RStudio中.我还正确定义了 coord_sf .就像我说的那样，此代码在更新之前一直有效.任何帮助将不胜感激.

I have not moved my shapefiles to another folder on my computer and they imported into RStudio correctly. I also have defined coord_sf correctly. Like I said, this code worked until the update. Any help would be appreciated.

推荐答案

我对您的代码做了一些小的修改，并且能够使用下面显示的r版本(R版本3.6.3)获得此图.这就是您期望看到的吗?

I made some minor modifications to your code and was able to get this plot using the r version shown below (R version 3.6.3). Is this is what you were expecting to see?

library(tidyverse)
library(ggspatial)

ggplot(data = datexample) +
  geom_point(aes(x = lon, y = lat, alpha = yearweek)) +
  facet_grid(cols = vars(animal)) +
  xlab("Longitude")+
  ylab("Latitude")
