rvnsims {rv} | R Documentation |
rvnsims
returns the number of simulations
stored in each component of its argument;
setnsims
sets the default number of simulations;
getnsims
retrieves the default number of simulations.
rvnsims(x) setnsims(n.sims) getnsims()
x |
an rv object. |
n.sims |
default number of simulations; must be at least 2. |
If the argument is a non-rv numeric vector, rvnsims
returns 1
(corresponding to a `constant') for each component.
The minimum number of default simulations is 2.
rvnsims
: a vector of integers.
setnsims
: previously set default number of simulations.
getnsims
: (integer) currently set default number of simulations.
