Details

• unlist0() is much like unlist() expect that name are not made to be unique.

• squash_vec() works differently

• squash_vec(): A vector of unique values and names

Examples

x <- list(a = 1:3, b = 2, c = 2:4)
y <- c(a = 1, b = 1, c = 1, d = 2, e = 3, f = 3)

# unlist0() doesn't force unique names
unlist(x)   # names: a1 a2 a3  b c1 c2 c3
unlist0(x)  # names: a a a  b c c c
unlist0(y)  # no change

# squash_vec() is like the inverse of unlist0() because it works on values
squash_vec(x)
squash_vec(y)
