calc_QSS_extinction_dif | R Documentation |

The Quasi-sign stability is estimated with of the community matrix (Jacobian) and characterizes
the linear stability of the network. This uses the function `calc_QSS()`

so it can take
into account the interaction strength if weights are present.

```
calc_QSS_extinction_dif(g, sp_list, nsim = 1000, ncores = 4, istrength = FALSE)
```

`g` |
igraph network |

`sp_list` |
list with the species/nodes we will delete for the comparison |

`nsim` |
number of simulations to calculate QSS |

`ncores` |
number of cores used to perform the operation |

`istrength` |
if TRUE takes the weight attribute of the network as interaction strength to calculate QSS. |

a data.frame with nsim rows for each species deleted with:

the node deleted

The QSS of the complete network for nsim simulations

The QSS of the network with the deleted node for nsim simulations

The difference between the two previous QSS

```
## Not run:
g <- netData[[1]]
# Generate random weights
#
V(g)$weight <- runif(vcount(g))
# Without interaction strength
#
calc_QSS_extinction_dif(g,V(g)$name[1:3],nsim=10,istrength = FALSE)
# With interaction strength
#
calc_QSS_extinction_dif(g,V(g)$name[1:3],nsim=10,istrength = TRUE)
## End(Not run)
