When a model fails to run, a red error message will be displayed at the bottom of the screen. A list of common error messages and what they mean can be found below.
|Type of Error||
Example of Error Message
|Invalid R expression used in formula, preventing it from being evaluated.||Error in parameter 'p_sick_nat', syntax error in R expression.|
|Formula refers to variable that does not exist, or that was undefined when formula was evaluated.||Error in parameter 'p_sick_new', Error: object 'p_death_new' not found|
|One or more variables contain circular references.||Circular reference in parameters In call: resolve_dependencies.default(parameters)|
|Model exceeds maximum allowed memory storage, preventing it from running.||Apologies, your model exceeded the maximum memory allowed. Please shorten the timeframe or reduce the number of tunnel states in your model|
|Transition probabilities in a Markov model are either < 0 or > 1.||Error in check_matrix(trans_matrix): Some transition probabilities are outside the interval [0 - 1]: cycle: 1, from: well, to: well cycle: 2, from: well, to: well cycle: 3|
|Transition probabilities in a Markov model in one or more states and/or cycles do not sum to 1.||Not all transition matrix rows sum to 1.
