assert/check/test/DistributionList

Validation checks to test if a given object is a list of Distributions.

testDistributionList(
  object,
  errormsg = "One or more items in the list are not Distributions"
)

checkDistributionList(
  object,
  errormsg = "One or more items in the list are not Distributions"
)

assertDistributionList(
  object,
  errormsg = "One or more items in the list are not Distributions"
)

Arguments

object

errormsg

custom error message to return if assert/check fails

Examples

testDistributionList(list(Binomial$new(), 5)) # FALSE
#> [1] FALSE
testDistributionList(list(Binomial$new(), Exponential$new())) # TRUE
#> [1] TRUE
