Create a series of nested LSEM if equations

Description

This function takes a series of conditions and corresponding values, and builds an equation consisting of nested if statements.

Usage

ls_eq_nestIfs(conditions, values, elseExpr, quoteValues = FALSE)

Arguments

conditions	The conditions - in the right order, i.e. in the produced expression if nested if statements, the first condition in this list will be checked first, then the second, etc.
values	The values corresponding to each condition (in the same order!).
elseExpr	The value to return if there are no matches.
quoteValues	Whether to use double quotes to quote the values.

Value

A character value.

Examples

### Relatively simple example with four levels of nesting
ls_eq_nestIfs(c("age.NAOK > 80",
                "age.NAOK > 65",
                "age.NAOK > 40",
                "age.NAOK > 20"),
              c("Respectable",
                "Roughly retired",
                "Roughly middle-aged",
                "Quite young"),
              "Very young",
              quoteValue=TRUE);
