Description Usage Arguments Details Examples
as_vector()
collapses a list of vectors into one vector. It
checks that the type of each vector is consistent with
.type
. If the list can not be simplified, it throws an error.
simplify
will simplify a vector if possible; simplify_all
will apply simplify
to every element of a list.

.x 
A list of vectors 
.type 
A vector mold or a string describing the type of the
input vectors. The latter can be any of the types returned by

.type
can be a vector mold specifying both the type and the
length of the vectors to be concatenated, such as numeric(1)
or integer(4)
. Alternatively, it can be a string describing
the type, one of: "logical", "integer", "double", "complex",
"character" or "raw".

as.list(letters) %>% as_vector("character")
# Or with a vector mold:
as.list(letters) %>% as_vector(character(1))
# Vector molds are more flexible because they also specify the
# length of the concatenated vectors:
list(1:2, 3:4, 5:6) %>% as_vector(integer(2))
# Note that unlike vapply(), as_vector() never adds dimension
# attributes. So when you specify a vector mold of size > 1, you
# always get a vector and not a matrix
