fact(x)
A vector of equal length of x
with class fact
and factor
. If
x
was ordered
, that class is added in between.
A vector of values
The order of the levels may be adjusted to these rules depending on the class
of x
:
character
The order of appearance
numeric
/integer
/Date
/POSIXt
By the numeric order
logical
As TRUE
, FALSE
, then NA
if present
factor
Numeric if levels can be safely converted, otherwise as they are
fact()
can be about 5 times quicker than factor()
or
as.factor()
as it doesn't bother sorting the levels for non-numeric data
or have other checks or features. It simply converts a vector to a factor
with all unique values as levels with NA
s included.
fact.factor()
will perform several checks on a factor to include NA
levels and to check if the levels should be reordered to conform with the
other methods. The fact.fact()
method simple returns x
.
as_ordered()
