Usage

condition(dist, interval, ...)

## S4 method for signature 'PointMassPrior,numeric'
condition(dist, interval, ...)

## S4 method for signature 'ContinuousPrior,numeric'
condition(dist, interval, ...)

Arguments

dist	a univariate distribution object
interval	length-two numeric vector giving the parameter interval to condition on
...	further optional arguments

Value

conditional Prior on given interval

Examples

tmp <- condition(PointMassPrior(c(0, .5), c(.3, .7)), c(-1, .25))
expectation(tmp, identity) # 0
