#' @title Food insecurity
#' 
#' @description \strong{NOTE:} this is not a function.
#'  
#'  This is a derived variable that uses the different food insecurity
#'  variables from all CCHS cycles to generate food_insecurity_der that is
#'  harmonized across all cycles. food_insecurity_der is a categorical variable
#'  with two categories:
#'  
#'  \enumerate{
#'   \item no food insecurity in the last 12 months 
#'   \item food insecurity in the last 12 months
#'  }
#'  
#' @details Food insecurity is measured differently across CCHS cycles. In 2001
#'  and 2003, FINF1 is used; in 2005, FSCDHFS is used; and in 2007
#'  to 2014, FSCDHFS2 is used. Each variable examines food insecurity in the
#'  household over the past 12 months, but use different base variables to
#'  derive food insecurity.  
#'  
#'  If you are using cchsflow for CCHS survey years that use consistent food
#'  insecurity variables, it is appropriate to use FINF1, FSCDHFS, or FSCDHFS2
#'  that are available on cchsflow. If you are using cchsflow for only the 2001
#'  and 2003 cycles, it is appropriate to use FINF1. If you are using cchsflow
#'  for only the 2005 cycle, FSCDHFS is appropriate. If you are using cchsflow
#'  for cycles between 2007 and 2014, FSCDHFS2 is appropriate. For multiple CCHS
#'  survey years that do not use the same food insecurity variables (i.e. using
#'  cchsflow for years 2001 to 2007), food_insecurity_der is recommended.

#' @param FINF1 variable used in 2001 and 2003 survey cycles indicating food

#'  insecurity & hunger in the last 12 months
