In cturbelin/ifnBase: InfluenzaNet Data Analysis Base

Check if two named list are compatible to merge

Description

To be compatible with template, mapping should follow these rules:

• only one value is mapped to a name

• new can add new name with new value, not already in old

• new cannot redefine a value with a new name (unless allow_override, not currently supported)

Usage

check_list_mapping(new, old, raise, only.errors = TRUE)

Arguments

new	list()
old	list()
raise	function(type, value, problem, message)
only.errors	only raise errors

Details

Overriding is allowed wraping the value with override function

Examples

## Not run: 
new = list("var1"="Q1", "var2"="Q2", "var3"="Q3", "var4"="Q1", "var5"="Q4")
old = list("var0"="Q0", "var1"="Q1", "var2"="Q4")
check_list_mapping(new, old, raise=raise)
# Returs list of errors

new = list("var1"="Q1", "var3"=override("Q2"))
old = list("var2"="Q2")
check_list_mapping(new, old, raise=raise) # Only throw warning

## End(Not run)
# The checks are transmitted to a provided function \code{\link{raise()}}
