calc_QSS_extinctions_seq | R Documentation |

This functions calculates the QSS `calc_QSS()`

for a sequence of incremental deletions of species (nodes)
given by the vector `seq`

, it does not produce secondary extinctions

```
calc_QSS_extinctions_seq(
g_del,
seq,
nsim = 1000,
ncores = 4,
istrength = FALSE
)
```

`g_del` |
igraph object for the deletion sequence |

`seq` |
vector or list with the nodes for the extinction sequence, the extinctions are incremental. |

`nsim` |
number of simulations used in QSS calculation |

`ncores` |
number of cores used to calculate QSS |

`istrength` |
parameter istrength for QSS function |

data frame with the number of remaining nodes, the connectance, the number unconnected of components, the median QSS, and the name of the last deleted node.
