Unlist and squash

Unlist without unique names; combine names for unique values

Usage

unlist0(x)

squash_vec(x, sep = ".")

Arguments

x

A vector of values

sep

A separation for combining names

Value

• unlist0(): a vector with the possibility of non-unique names

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

Details

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

• squash_vec() works differently

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
#> a1 a2 a3  b c1 c2 c3 
#>  1  2  3  2  2  3  4 
unlist0(x)  # names: a a a  b c c c
#> a a a b c c c 
#> 1 2 3 2 2 3 4 
unlist0(y)  # no change
#> a b c d e f 
#> 1 1 1 2 3 3 

# squash_vec() is like the inverse of unlist0() because it works on values
squash_vec(x)
#>     a a.b.c   a.c     c 
#>     1     2     3     4 
squash_vec(y)
#> a.b.c     d   e.f 
#>     1     2     3
