Function interp_lm 

fn interp_lm(
    args: &[RValue],
    named: &[(String, RValue)],
    _context: &BuiltinContext<'_>,
) -> Result<RValue, RError>

Fit a linear model using ordinary least squares.

Supports simple and multiple linear regression with formula syntax. The formula y ~ x fits a simple regression; y ~ x1 + x2 fits multiple regression. An intercept is always included.

@param formula a formula specifying the model (e.g. y ~ x) @param data a data frame containing the variables in the formula @return a list of class “lm” with components: coefficients, residuals, fitted.values, and call
