mixtures of fixed and continuous distributions errors

Code
  mixture(bernoulli(0.5), normal(0, 1), weights = weights)
Condition
  Error in `initialize()`:
  ! Cannot construct a mixture distribution from a combination of discrete and continuous distributions

mixtures of multivariate and univariate errors

Code
  mixture(multivariate_normal(zeros(1, 3), diag(3)), normal(0, 1, dim = c(1, 3)),
  weights = weights)
Condition
  Error in `initialize()`:
  ! Cannot construct a mixture from a combination of multivariate and univariate distributions

mixtures of supports errors

Code
  mixture(normal(0, 1, truncation = c(0, Inf)), normal(0, 1), weights = weights)
Condition
  Error in `initialize()`:
  ! Component distributions must have the same support
  However the component distributions have different support:
  "0 to Inf vs. -Inf to Inf"

Code
  mixture(lognormal(0, 1), normal(0, 1), weights = weights)
Condition
  Error in `initialize()`:
  ! Component distributions must have the same support
  However the component distributions have different support:
  "0 to Inf vs. -Inf to Inf"

incorrectly-shaped weights errors

Code
  mixture(normal(0, 1), normal(0, 2), weights = weights)
Condition
  Error in `initialize()`:
  ! The first dimension of weights must be the number of distributions in the mixture (2)
  However it was 1

mixtures with insufficient distributions errors

Code
  mixture(normal(0, 2), weights = weights)
Condition
  Error in `initialize()`:
  ! `mixture()` must be passed at least 2 distributions
  The number of distributions passed was: 1

Code
  mixture(weights = weights)
Condition
  Error in `initialize()`:
  ! `mixture()` must be passed at least 2 distributions
  The number of distributions passed was: 0
