What to convert |
method |
The conversion method:
|
to
can be one of several values. Firstly the default of default
calls several additional functions that attempt to resolve a transformation
from a character
vector to a different type. It is recommended for users
to enter their own specifications instead. Secondly, a function
(with a
single argument) can be passed which will then be applied directly to x
.
Third, a prototype value can be passed. This might be risky for special
types. Here, the values of mode()
, storage.mode()
, attributes()
, and
class()
are captured and reassigned from to
to x
. A special check is
implemented for factor
s to more safely convert. Lastly, NULL
will do
nothing and will simply return x
.
