我想在 Vertica 中创建 R 功能，我收到了错误消息。 任何帮助或线索都会被高度关注
dbadmin=> create transform function pred as language 'R' name 'pred' library predLb;
ROLLBACK 3399: Failure in UDx RPC call InvokeGetUdxType(): Error calling getUdxType() in User Defined Object [predict] at [/scratch_a/release/16125/vbuild/vertica/OSS/UDxFence/vertica-udx-R.cpp:209], error code: 0, message: Error happened in getUdxType : Exception in processing required attribute udxtype in the factory function : no applicable method for 'predict' applied to an object of class "NULL"

答案 0 :(得分：0)
找到答案！ 实际上R libs没有任何问题，它只是一个拼写问题！ :(而不是我自己。我不会审查R Udx代码。 R函数名称是pred不同。
