add_Time_col: Create a Time-of-Day column in the dataset

In LightLogR: Process Data from Wearable Light Loggers and Optical Radiation Dosimeters

Create a Time-of-Day column in the dataset

Description

Create a Time-of-Day column in the dataset

Usage

add_Time_col(
  dataset,
  Datetime.colname = Datetime,
  Time.colname = Time,
  output.dataset = TRUE
)

Arguments

dataset	A light logger dataset. Expects a dataframe. If not imported by LightLogR, take care to choose a sensible variable for the Datetime.colname.
Datetime.colname	column name that contains the datetime. Defaults to "Datetime" which is automatically correct for data imported with LightLogR. Expects a symbol. Needs to be part of the dataset. Must be of type POSIXct.
Time.colname	Name of the newly created column. Expects a symbol. The default(Time) works well with other functions in LightLogR. Will overwrite existing columns of identical name.
output.dataset	should the output be a data.frame (Default TRUE) or a vector with hms (FALSE) times? Expects a logical scalar.

Value

a data.frame object identical to dataset but with the added column of Time-of-Day data, or a vector with the Time-of-Day-data

Examples

sample.data.environment %>% add_Time_col()
