cm_range2long: Transform Codes to Start-End Durations

Description

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

Usage

cm_range2long(..., 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 data frame of start and end spans for each code.

    DD = qcv(terms="")
)

## General ldots Approach
(dat <- cm_range2long(foo, foo2, v.name = "time"))
plot(dat)

## Specify `object` Approach
cm_range2long(object=list(foo=foo))
cm_range2long(object=list(foo=foo, foo2=foo2), v.name="time")
cm_range2long(object=list(a=foo, b=foo2), v.name="time")
# }
