cm_time2long: Transform Codes to Start-End Times

Description

Transforms the range coding structure(s) from cm_time.temp (in list format) into a data frame of start and end times in long format.

Usage

cm_time2long(..., v.name = "variable", list.var = TRUE, debug = TRUE,
  object = NULL)

Arguments

v.name

An optional name for the column created for the list.var argument

list.var

logical. If TRUE creates a column for the data frame created by each time.list passed to cm_t2l.

debug

logical. If TRUE debugging mode is on. cm_time2long will return possible errors in time span inputs.

object

A list of list object(s) generated by cm_time.temp.

…

List object(s) in the form generated by cm_time.temp.

Value

Generates a dataframe of start and end times for each code.

## General ldots Approach
cm_time2long(bar1)
cm_time2long(bar1, bar2, v.name="time")

## Specify `object` Approach
cm_time2long(object=list(bar1=bar1))
cm_time2long(object=list(bar1=bar1, bar2=bar2), v.name="time")
cm_time2long(object=list(a=bar1, b=bar2), v.name="time")
# }
