RAnEn::mergeList combine two lists. It does not allow names in conflict unless the name is further a list. This is similar to a depth-first copy for list variables.
mergeList(from, to, names)A list to copy from
A list to copy to
the names to copy, usually names(from)
library(RAnEn)
from <- list(C = list(C = 3, D = list(A = 1)), D = 3)
to <- list(A = 1, B = 2, C = list(A = 1, B = 2))
merged <- mergeList(from, to, names(from))
print(from, recursive = T)
#> $C: list: [2]
