The key is in the help page for apply. It says (in part):
In all cases the result is coerced by Œas.vector¹ to one of the
basic vector types before the dimensions are set, so that (for
example) factor results will be coerced to a character array.
So although as.polynomial() returns
it looks like as. polynomial merely stores the coefficients of the
polynomial.
"Internally, polynomials are simply numeric coefficient vectors of
class "polynomial". "
If you really want to print it in the form you want try this.
m <- matrix(rnorm(3000),1000,3)
apply(m, 1, function(x){

I would like to convert the contents
