is.na.rv returns the distribution (random variable) of the indicator
function of missing data. rv.all.na returns TRUE if all
components of the argument vector are completely missing. rv.any.na
returns TRUE if any component of the argument vector has missing
values.
Usage
# S3 method for rv
is.na(x)
Arguments
x
an rv object
Value
is.na.rv returns a "Bernoulli" random vector of the same
length and dimension as those of x.
rv.all.na and rv.any.na return TRUE or FALSE
(single value).
Details
Internally, is.na.rv applies the function is.na to each
simulation of each component of the argument vector.
