cm_2long: A Generic to Long Function

In qdap: Bridging the Gap Between Qualitative Data and Quantitative Analysis

A Generic to Long Function

Description

A wrapper for cm_df2long, cm_range2long, and cm_time2long that automatically detects the objects being read and outputs the correct form and class.

Usage

cm_2long(..., v.name = "variable", list.var = TRUE, debug = TRUE)

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.
...	list object(s) in the form generated by cm_df.temp, cm_range.temp, or cm_time.temp.

Value

Returns a long data.frame of the correct cm_XXX classes.
