如何从文本版本加载光栅并避免此错误？这是一个错误，原因是
.RasterFile光栅层x <- new(".RasterFile")
validObject(x)
#Error in datanotation %in% c("LOG1S", "INT1S", "INT2S", "INT4S", "INT1U", :
# object 'datanotation' not found
x问这个问题的原因是我认为我遇到了与光栅内容相关的问题，我想用一种简单的方法发布光栅的结构以及一个问题等等。无论如何都解决了我的问题，所以实际上不再需要这个了。我想这是一件不寻常的事情，因为大多数人只会在光栅文件上发布一个下载链接，如果需要它作为支持问题的数据，但我觉得问题应该尽可能独立，如果可能的话，不要依赖外部链接，但通常要做的是在内存中创建一个光栅层，如r
x <- new(".RasterFile")
validObject(x)
#Error in datanotation %in% c("LOG1S", "INT1S", "INT2S", "INT4S", "INT1U", :
# object 'datanotation' not found
