further arguments to be passed to or from other methods.
For the internal default method these can include:
times
an integer-valued vector giving the
(non-negative) number of times to repeat each element if of
length length(x), or to repeat the whole vector if of
length 1. Negative or NA values are an error. A
double vector is accepted, other inputs being coerced to
an integer or double vector.
length.out
non-negative integer. The desired length of the
output vector. Other inputs will be coerced to a double
vector and the first element taken. Ignored if NA or invalid.
each
non-negative integer. Each element of x
is repeated each times. Other inputs will be coerced to
an integer or double vector and the first element taken. Treated as
1 if NA or invalid.
