Calculate daily maximum-8-hour ozone in batch

Calculates daily maximum-8-hour ozone in batch

Usage

dm8n_batch(
  df,
  starthour = 0,
  endhour = 16,
  nh = 6,
  nc = 14,
  na.rm = TRUE,
  outputmode = 1
)

Arguments

df

dataframe of time series for ozone and other related parameters.

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.

Value

a dataframe depends on the value of 'outputMode'. Value 1 will output 1 list which incudes 1 table (maximum-8-hour ozone). 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).
