r：holtwinters函数的预测

Question

我正在尝试每天预测数据。 如果我在r中使用holtwinters函数，我收到警告消息而无法执行输出

我使用了以下代码

我的数据如下

version: "2.1"

services:
  jobmanager:
    image: flink
    expose:
      - "6123"
    ports:
      - "8081:8081"
    command: jobmanager
    volumes:
      - /c/Users/XYZ/playground/flink/shared/log4j.properties:/opt/flink/conf/log4j-console.properties
    environment:
      - JOB_MANAGER_RPC_ADDRESS=jobmanager
      - FLINK_ENV_JAVA_OPTS=-Dlog.file=/opt/flink/log/jobmanager.log

  taskmanager:
    image: flink
    expose:
      - "6121"
      - "6122"
    depends_on:
      - jobmanager
    command: taskmanager
    links:
      - jobmanager:jobmanager
    volumes:
      - /c/Users/XYZ/playground/flink/shared/log4j.properties:/opt/flink/conf/log4j-console.properties
    environment:
