appendLists {omnibus}

Append values to elements of a list from another list

Description

This function "adds" two lists with the same or different names together. For example, if one list is as l1 <- list(a=1, b="XYZ") and the second is as l2 <- list(a=3, c=FALSE), the output will be as list(a = c(1, 3), b = "XYZ", c = FALSE). All elements in each list must have names.

Usage

appendLists(...)

Arguments

...

Two or more lists. All elements must have names.

Details

If two lists share the same name and these elements have the same class, then they will be merged as-is. If the classes are different, one of them will be coerced to the other (see *Examples*). The output will have elements with the names of all lists.

Value

A list.
