Arguments
p
scale or vector of probabilities at which the quantile function needs to be computed
sigma
the value of sigma parameter of the lognormal distribution, must be positive
theta
the value of theta parameter, the cutoff point, must be positive
spec
the specific distribution with which the lognormal distribution should be composited with
log.p
if TRUE then quantiles are returned for exp(p)
lower.tail
if TRUE then quantiles are returned for p else quantiles are returned for 1-p
