Special value predicates for random variables

Compute special value predicates (checking for finite / infinite values, NaN, and NA) on all draws within a random variable, returning a random variable.

rvar_is_finite(x)

rvar_is_infinite(x)

rvar_is_nan(x)

rvar_is_na(x)

Arguments

x

(rvar) An rvar.

Value

A logical rvar of the same length as the input.

Details

These functions return a new rvar that is the result of applying is.finite(), is.infinite(), is.nan(), or is.na() to every draw in the input random variable.

See also

rvar-summaries-over-draws for summary functions across draws, including implementations of is.finite(), is.infinite(), is.nan(), and is.na() for rvars.

Examples

x <- rvar(c(1, Inf, -Inf, NaN, NA))
x
#> rvar<5>[1] mean ± sd:
#> [1] NaN ± NA 

rvar_is_finite(x)
#> rvar<5>[1] mean ± sd:
#> [1] 0.2 ± 0.45 
rvar_is_infinite(x)
#> rvar<5>[1] mean ± sd:
#> [1] 0.4 ± 0.55 
rvar_is_nan(x)
#> rvar<5>[1] mean ± sd:
#> [1] 0.2 ± 0.45 
rvar_is_na(x)
#> rvar<5>[1] mean ± sd:
#> [1] 0.4 ± 0.55
