# as_vector

##### Coerce a list to a vector

`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.

##### Usage

`as_vector(.x, .type = NULL)`simplify(.x, .type = NULL)

simplify_all(.x, .type = NULL)

##### Arguments

- .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

`typeof()`

, or "numeric" as a shorthand for either "double" or "integer".

##### Details

`.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".

##### Examples

```
# NOT RUN {
# Supply the type either with a string:
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
# }
```
