R 包警告：为“方向”找到多个方法表

Question

我正在为空间数据维护一个 R 包。当我在 R-devel (Windows) 上运行检查时，我得到："Warning: multiple methods tables found for 'direction'"，它禁止我重新提交我的 R 包。我已经检查过，只有一个函数 direction() 来自 raster 包 - 我没有明确导入的包，但在 sf 中建议我这样做。关于这可能是什么/解决方法的任何想法？

Answer 1

> library(sp)
> library(raster)
Warning messages:
1: multiple methods tables found for 'direction' 
2: multiple methods tables found for 'gridDistance' 

新会话：

> raster::direction
standardGeneric for "direction" defined from package "raster"

function (x, ...) 
standardGeneric("direction")
<bytecode: 0x8163a60>
<environment: 0x81349e0>
Methods may be defined for arguments: x
Use  showMethods(direction)  for currently available ones.

看起来 raster 和 terra 都定义了这些泛型，terra 1.5-12 刚刚发布。解析度： https://github.com/rspatial/terra/issues/485#issuecomment-1012466626，在terra之后重新安装raster。
