R Documentation

Average By Time

Description

Function used to average data to new time resolution using the dplyr grouping. It is an attempt to be more efficent than openair::timeAverage to be used when dealing with unusually large datasets. It is certainly nowhere near as robust.
Use at your own risk

Usage

average_by_time(
  df,
  time_stamp = c("floor", "round", "ceiling")[1],
  res = "1 min",
  .f = mean,
  time_col = "date",
  ...
)

Arguments

`df`	data.frame
`time_stamp`	"floor" "round" or "ceiling". How is the time_stamp rounded to the resolution? conside the implication on the resulting timestamp. Floor is default, giving a timestamp that referes to the begining of the averaging period
`res`	time resolution to round to. Use lubridate "unit" format. Default "1 min"
`.f`	function to use when using summarise_all. default mean
`time_col`	what column contains the time information, default date
`...`	extra arguments to pass to .f
