evaluate_expression function

evaluate_expression

Evaluate expression using model

Calculate the value of expression for each data record. The expression can contain dataset columns, variables in model and population parameters. If the model has parameter estimates these will be used. Initial estimates will be used for non-estimated parameters.

evaluate_expression(model, expression, parameter_estimates = NULL)

Arguments

• model: (Model) Pharmpy model
• expression: (str or numeric or Expr) Expression to evaluate
• parameter_estimates: (list(str=numeric) (optional)) Parameter estimates to use instead of initial estimates

Returns

(data.frame) A series of one evaluated value for each data record

Examples

## Not run:

model <- load_example_model("pheno")
results <- load_example_modelfit_results("pheno")
pe <- results$parameter_estimates
evaluate_expression(model, "TVCL*1000", parameter_estimates=pe)
## End(Not run)
