Append values to elements of a list from another list

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.

Value

A list.

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.

# same data types for same named element
l1 <- list(a=1, b="XYZ")
l2 <- list(a=3, c=FALSE)

#> 
#> $c
#> [1] FALSE

# different data types for same named element
l1 <- list(a=3, b="XYZ")
