## Estimating CoDa regression models

### Description

This is a thin wrapper around `lm()`

followed by `ToSimplex()`

, which
allows to create a lmCoDa object in one step.

### Usage

```

```

### Arguments

`formula` |
as in |

`data` |
as in |

`...` |
arguments passed on to |

an object of class "lm" and "lmCoDa" if the formula include at least one log-transformation

### Examples

```
# XY-compositional model
res <- lmCoDa(
ilr(cbind(left, right, extreme_right)) ~
ilr(cbind(Educ_BeforeHighschool, Educ_Highschool, Educ_Higher)),
data = head(election, 20))
# X-compositional model
res <- lmCoDa(YIELD ~ PRECIPITATION + ilr(TEMPERATURES), data = head(rice_yields, 20))
```
