将R randomForest对象保存到SQL数据库

Question

Is there a way to save a randomForests object (or other large objects) from R into a SQL database. The only thing I can think of is to dsub the object and save it as a varchar(max) but was wondering if there's another way.

Answer 1

The native way is to serialize the object using serialize() . If your database supports binary objects, you can use the binary serialization, otherwise you can use rawToChar(serialize(x, NULL, ascii=TRUE)) to obtain a string.

Note that dput is inherently dangerous for storage because it allows arbitrary execution attacks.
