`df` |
dataframe of time series for ozone and other related parameters. |

`colid` |
column index for date-time. By default, it equals to 1. |

`colio` |
column index for ozone. By default, it equals to 2. |

`starthour` |
numeric, start hour for calculating 8-hour ozone. By default, it equals to 0. |

`endhour` |
numeric, end hour for calculating 8-hour ozone. By default, it equals to 16 which means averaging ozone between 16~23. |

`nh` |
numeric. The number of effective hourly concentrations per 8-hour period. |

`nc` |
numeric. The number of effective 8-hour average concentrations per day. |

`na.rm` |
logical. Should missing values (including NaN) be omitted from the calculations? |

`outputmode` |
numeric, the format of the output, possible value: 1 or 2. See 'value' for the results of filling in 1 or 2. |

`unitlb` |
labels for y axis of dma8 plot. By default, it equals to NA. If set this parameter, the order of species should same as that in the dataframe. |

This function can calculate daily maximum-8-hour ozone and other parameters corresponding to it.

a dataframe depends on the value of 'outputMode'. Value 1 will output 1 list which incudes 1 table (maximum-8-hour ozone) and 1 plot (dma8 plot). Value 2 will output 1 list which contains 4 tables (8-hour ozone, statistics of the number of effective hourly concentrations in each 8-hour average concentration, statistics of the number of effective 8-hour average concentrations in each day, maximum-8-hour ozone) and 1 plot (dma8 plot).
