`dynformula`

, `pht`

, `plm.data`

, and `pvcovHC`

are
deprecated functions which could be removed from plm in a near future.

```
pvcovHC(x, ...)
plm.data(x, indexes = NULL)
dynformula(formula, lag.form = NULL, diff.form = NULL, log.form = NULL)
## S3 method for class 'dynformula'
formula(x, ...)
## S3 method for class 'dynformula'
print(x, ...)
```

`x` |
an object of class |

`...` |
further arguments. |

`indexes` |
a vector (of length one or two) indicating the (individual and time) indexes (see Details); |

`formula` |
a formula, |

`lag.form` |
a list containing the lag structure of each variable in the formula, |

`diff.form` |
a vector (or a list) of logical values indicating whether variables should be differenced, |

`log.form` |
a vector (or a list) of logical values indicating whether variables should be in logarithms. |

`data` |
a |

`dynformula`

was used to construct a dynamic formula which was the
first argument of `pgmm`

. `pgmm`

uses now multi-part formulas.

`pht`

estimates the Hausman-Taylor model, which can now be estimated
using the more general `plm`

function.

`plm.data`

is replaced by `pdata.frame`

.

`pvcovHC`

is replaced by `vcovHC`

.

`detect_lin_dep`

was renamed to `detect.lindep`

.
