r - xts包中的reclass函数有什么作用？

Question

我以为它是为了将 xts 对象转换为其原始类，但是当我将 xts 对象传递给它之后，它并没有给我返回原始对象。它有什么用？

我的尝试

data(sample_matrix)
class(sample_matrix)
#"matrix"
class(reclass(as.xts(sample_matrix)))
#"xts" "zoo"

来自文档

try.xts and reclass are functions that enable external developers access to the reclassing tools within xts to help speed development of time-aware functions, as well as provide a more robust and seemless end-user experience, regardless of the end-user's choice of data-classes.

如果您使用 try.xts 将 xtsible 对象转换为 xts 对象，reclass 或 Reclass 两者都应该能够将其转换回其原始类，并且所有属性完好无损。

class(Reclass(try.xts(sample_matrix)))
## [1] "matrix"

class(reclass(try.xts(sample_matrix)))
## [1] "matrix"
