unsplit
method for List object and split<-
method for Vector object.## S3 method for class 'List':
unsplit(value, f, drop = FALSE)
## S3 method for class 'Vector':
split(x, f, drop = FALSE, ...) <- value
factor
or list
of factorsX
FUN
unsplit
unlists value
, where the order of the returned
vector is as if value
were originally created by splitting that
vector on the factor f
. split(x, f, drop = FALSE) <- value
: Virtually splits x
by
the factor f
, replaces the elements of the resulting list with the
elements from the list value
, and restores x
to its original
form. Note that this works for any Vector
, even though split
itself is not universally supported.
