inspect_bfactor_log: Validate vectors of logarithmic Bayes factors
In inspector: Validation of Arguments and Objects in User-Defined Functions

Description Usage Arguments Details Value See Also Examples

inspect_bfactor_log checks if an object is a numeric vector of valid logarithmic Bayes factor values. This can be useful to validate inputs, intermediate calculations or outputs in user-defined functions.

1	inspect_bfactor_log(x, allow_nas = TRUE, warning_nas = TRUE)

`x`	An arbitrary object.
`allow_nas`	Logical value. If `TRUE` then `NA` and `NaN` values in `x` are allowed. If `FALSE`, execution is stopped and an error message is thrown in case there are `NA` or `NaN` values in `x`.
`warning_nas`	Logical value. If `TRUE` then the presence of `NA` or `NaN` values in `x` generates a warning message. `NA` and `NaN` values pass silently otherwise (if `allow_nas` is `TRUE`).

inspect_bfactor_log conducts a series of tests to check if x is a numeric vector of valid logarithmic Bayes factor values. Namely, inspect_bfactor_log checks if:

x is NULL or empty.
x is an atomic vector.
x is numeric.
x has NA or NaN values.

inspect_bfactor_log does not return any output. There are three possible outcomes:

The call is silent if:
- x is a numeric vector of valid logarithmic Bayes factor values and there are no NA or NaN values in x.
- x is a numeric vector of valid logarithmic Bayes factor values, there are some NA or NaN values in x, allow_nas is set to TRUE and warning_nas is set to FALSE.
An informative warning message is given if x is a numeric vector of valid logarithmic Bayes factor values, there are some NA or NaN values in x and both allow_nas and warning_nas are set to TRUE.
An informative error message is thrown and the execution is stopped if:
- x is not a numeric vector of valid logarithmic Bayes factor values.
- x is a numeric vector of valid logarithmic Bayes factor values, there are some NA or NaN values in x and allow_nas is set to FALSE.

inspect_bfactor to check if an object is a numeric vector of valid Bayes factor values.
bfactor_log_interpret for the interpretation of the logarithms of Bayes factors.
inspect_bfactor_scale to check if an object is a Bayes factor interpretation scale.
inspect_log_base to check if an object is an eligible logarithmic base.

# Calls that pass silently:
x1 <- c(0, 0.5, 1, 10, 50, 100)
x2 <- c(NA, 0.5, 1, 10, 50, 100)
inspect_bfactor_log(x1)
inspect_bfactor_log(x2, warning_nas = FALSE)
inspect_bfactor_log(x2, allow_nas = TRUE, warning_nas = FALSE)

# Call that throws an informative warning message:
y <- c(0.1, 0.2, NA, 0.4, 0.5)
try(inspect_bfactor_log(y))
try(inspect_bfactor_log(y, warning_nas = TRUE))
try(inspect_bfactor_log(y, allow_nas = TRUE, warning_nas = TRUE))

# Calls that throw informative error messages:

  NULL, TRUE, factor(.5), matrix(0.5),
  "0.5", list(0.5), numeric(0), NA, NaN
