In gdesve/epifield: Functions for field epidemio

Description

epiorder Rearrange order of factor variable to produce classical epi table 1/0 Yes/No +/-

Usage

epiorder(var, mode = "yesno", levels = NULL, update = TRUE, reverse = FALSE)

Arguments

var	Variable to reorder (will be converted as factor).
mode	Label plan for the new factor variable "yesno" for Yes, No "10" for 1, 0 "+-" for +,- "truefalse" for TRUE, FALSE or any set of two labels on the form c("A","B")
levels	Custom set of levels as vector : c(1,0) This levels will replaced by the lables then levels and labels should have the same length and the same order
update	if TRUE (the default) Then the original dataset is updated with new value The recoded column is replaced by the returned value With this option, there is no need to reassign the retruned value, but original data are lost.
