Transform Codes to Start-End Durations

Usage

cm_df2long(df.temp.obj, v.name = "variable", list.var = TRUE, code.vars = NULL, no.code = NA, add.start.end = TRUE, repeat.vars = NULL, rev.code = FALSE)

Arguments

df.temp.obj
A character vector of names of object(s) created by cm_df.temp, a list of cm_df.temp created objects or a data frame created by cm_df.temp.
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.
code.vars
A character vector of code variables. If NULL uses all variables from the first column after the column named word.num.
no.code
The value to assign to no code; default is NA.
add.start.end
logical. If TRUE adds a column for start and end times.
repeat.vars
A character vector of repeated/stacked variables. If NULL uses all non code.vars variables.
rev.code
logical. If TRUE reverses the order of code.vars and no.code variables.

Transform Codes to Start-End Durations

Value

Generates a data frame of start and end times for each code.

Description

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