dheft(q, fit) 
hheft(q, fit) 
pheft(q, fit) 
qheft(p, fit) 
rheft(n, fit) 

Arguments

q

vector of quantiles. Missing values (NAs) are allowed.

p

vector of probabilities. Missing values (NAs) are allowed.

n

sample size. If length(n) is larger than 1, then length(n) random values are returned.

fit

heft object, typically obtained from heft.

Details

Elements of q or p that are missing will cause the corresponding elements of the result to be missing.

Value

Densities (dheft), hazard rates (hheft), probabilities (pheft), quantiles (qheft), or a random sample (rheft) from a heft object.
