无法在栅格上使用任何功能

Question

我已将光栅图像 (.tif) 上传到 R 中，它似乎加载正常，但我无法使用它的任何功能。库调用和下面发布的示例代码。

[在这里添加文本，因为没有它堆栈交换不允许我发帖，但我没有更多相关信息要添加]

library(sp)
library(ggplot2)
library(raster)

从回溯中，错误来自

crs<-

函数。您的

pkg:terra

版本已过时。你应该更新它。我的版本是 terra_1.7-23，我无法重现错误。当前版本

terra

::

crs<-

的帮助页面说“warn”是一个命名参数，默认为

FALSE

.
