Pre-validation of data and parameters

Before passing data to `rtmb_model`, it checks for the presence of R-specific data types (such as data.frame) and missing values, and outputs errors or warnings accordingly.

Usage

validate_data(dat_list)

Arguments

dat_list

A list of data to be passed to the model (usually containing matrices or numeric vectors).

Value

Returns invisible `NULL` on success. Interrupts execution with `stop()` or issues `warning()` if issues are found.

Details

RTMB's automatic differentiation engine requires pure `matrix` or `numeric` types. If a user mistakenly passes a `data.frame`, incomprehensible errors occur during the construction of the computation graph. This function catches such issues in advance.
