drop,rvar-method {posterior} | R Documentation |
Delete the dimensions of an rvar
which are of size one. See base::drop()
## S4 method for signature 'rvar' drop(x)
x |
(rvar) an |
An rvar
with the same length as x
, but where any entry equal to 1
in dim(x)
has been removed. The exception is if dim(x) == 1
, in which
case dim(drop(x)) == 1
as well (this is because rvar
s, unlike numeric
s,
never have NULL
dimensions).
