dm8n_np: Calculate daily maximum-8-hour ozone without printing plot

In GlossyBoat/foqat: Field Observation Quick Analysis Toolkit

Calculate daily maximum-8-hour ozone without printing plot

Description

Calculates daily maximum-8-hour ozone from ozone observation data without printing plot

Usage

dm8n_np(
  df,
  colid = 1,
  colio = 2,
  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.
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.

Details

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

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).

Examples

dm8n_np(aqi,colio=6)
