fuse: Merges (fuses) lists recursively

In avidclam/avidstart: Useful R helper functions for quick start of data analysis projects

Description

Merges lists so that alike-named elements at the same level of list hierarchy receive the values that come last in the list of arguments.

Usage

fuse(...)

Arguments

...	lists to be fused

Details

Side effect of this implementation is that elements get sorted on every level.

Value

merged list (or vector if arguments are vectors)

Examples

fuse(1, 2) # Returns 2
# Example 1
# x = 1 gets replaced by x = list(z = NULL)
# y = 0 gets replaced by y = 2
fuse(list(y = 0), list(x = 1, y = 2), list(x = list(z = NULL)))
# ... and the result equals list(x = list(z = NULL), y = 2)
#
# Example 2
fuse(0, list(NULL), NA, NULL) # yields NA
# ... because the last NULL is ignored 
# and arguments 0, list(NULL) and NA are fused as unnamed 
# and on the same level of list hierarchy
