加载数据“命名空间不可用”

Question

我收到了一堆用R的save函数保存的数据。

当我尝试加载它时，我收到了关于命名空间的警告，因此最终出现错误。有没有办法对其进行排序并恢复数据？

> load('mydata')
Warning: namespace ‘BMP’ is not available and has been replaced
by .GlobalEnv when processing object ‘res’
Error: ReadItem: unknown type 0, perhaps written by later version of R

我知道BMP是用于生成数据的函数，res是mydata中包含的元素之一。
