inspect_par_beta: Validate parameters for the Beta distribution

Description

inspect_par_beta checks if an object is an eligible vector of parameters for the Beta distribution. This can be useful to validate inputs, intermediate calculations or outputs in user-defined functions.

Usage

inspect_par_beta(x)

Arguments

x

An arbitrary object.

Value

inspect_par_beta does not return any output. There are two possible outcomes:

• The call is silent if x is an eligible vector of parameters for the Beta distribution.

• An informative error message is thrown otherwise.

Details

inspect_par_beta conducts a series of tests to check if x is an eligible vector of parameters for the Beta distribution. Namely, inspect_par_beta checks if:

• x is NULL or empty.

• x is an atomic vector

• x is numeric

• x has length 2

• x has NA or NaN values.

• All elements of x are positive.

See Also

• inspect_par_bernoulli to validate parameters for the Bernoulli/Binomial distribution.

• inspect_par_multinomial to validate parameters for the Multinomial distribution.

• inspect_par_dirichlet to validate parameters for the Dirichlet distribution.

• inspect_par_haldane to validate parameters for the Haldane distribution.

Examples

# NOT RUN {
# Calls that pass silently:
x1 <- c(1, 1)
x2 <- c(2, 5)
inspect_par_beta(x1)
inspect_par_beta(x2)

# Calls that throw an informative error message:
mylist <- list(
  NULL, 1, factor(1, 1),
  matrix(c(1, 1)), c("1", "1"), list(1, 1), c(1, NA),
  c(1, NaN), c(TRUE, FALSE), numeric(0), c(-1, 1)
