# get_y: get y (right hand of var) In linear.tools: Manipulate Formulas and Evaluate Marginal Effects

## Description

get y (right hand of var)

## Usage

 `1` ```get_y(Formula, method = c("raw", "model", "coeff")) ```

## Arguments

 `Formula` a formula to be paste. `method` either `'raw','model'`, or `'coeff'`, to decide what kind variables to show. Default is 'raw'. See section Detials below.

## Details

What do 'raw' variable, 'model' variable, and 'coeff' variable mean?

• raw var is the underlying variable without any calculation or transformation.

• model var is the underlying variable with calculations or transformation.

• coeff var is the coefficient variable in the model output. So only evaluated model has coeff var.

In the formula, `log(y) ~ x1 + x2`, we have: 'raw' variable for `y`: `y` 'model' variable for `y`: `log(y)` 'coeff' variable for `y`: `log(y)`

More examples see the sample code below.

## Examples

 ``` 1 2 3 4 5 6 7 8 9 10 11``` ```get_y(log(price) ~sdfsf + dsa ) get_y(log(price) ~ sdfsf + dsa, method = "model") get_y(log(price) ~ sdfsf + dsa, method = "coeff") # same as model var in the get_y() case # can deal with un-regular formula get_y(log(price) ~sdfsf + dsa ~ dsad) get_y(log(price) ~ sdfsf + dsa ~ dsad, method = "coeff") get_y(log(price) ~ sdfsf + dsa ~ dsad, method = "model") model_dirty = model = lm(price~ I(carat^ 2) + cut - carat:table - cut ,ggplot2::diamonds) get_y(model_dirty) ```
